CHAPTER XIV

THE SECRET OF THE GREEN ROOM

I do not know just what my auditors expected in the way of an

explanation of the mystery when they followed me to the green

room--possibly some well-constructed or finely drawn theory. When I

pointed to the chandelier, they all looked a bit nonplused, and nobody

said anything for several moments. Then McQuade remarked, in his quiet

voice, with a shade of comprehension in his tone and expression: "How do

you make that out, Sir?"

The chandelier to which I had pointed was an old-fashioned one, of the

kind in general use in the early fifties. It was, I fancied, originally

made for a room with a somewhat higher ceiling. The ceilings in the

wings of The Oaks were unusually low, and the extreme lower end of the

chandelier extended to a point not much over six feet from the floor. I

judged this, because I am myself five feet eleven, and I could just pass

beneath it without striking it. It hung in the center of the room, and

about three feet from the side of the bed, which, on account of its

great size, extended far out from the wall against which it was placed.

The chandelier was of dark bronze or bronzed iron, and consisted of a

heavy central stem, from the lower end of which extended four

elaborately carved branches, supported by heavy and useless chains

reaching to a large ball about midway up the stem. Below the point from

which these four arms sprung was a sort of circular bronze shield, or

target, and from the lower face of this, in the center, projected an

octagonal ornamental spike, about two and a half inches long,

terminating in a sharp point. The whole thing was ugly and heavy, and

seemed in design more suitable to a hall or library than a bedroom.

Almost directly beneath it, but somewhat nearer to the side of the bed,

stood the low bench or stool, not over five inches high, the use of

which I have already mentioned. I explained the tragedy to the detective

and the others as I knew it must have happened.

"Last night," I said, "I was unable to open either the window in the

south or that in the west wall, because of the driving rain. The same

conditions, as you will remember, existed upon the fatal night which Mr.

Ashton spent here. For some reason, which I hope to explain presently,

we were both nearly suffocated while asleep, and rose suddenly in bed,

with but one thought, one desire, to get a breath of fresh air. The

window in the west wall, directly opposite the bed, attracted us. In Mr.

Ashton's case, no doubt, the face of Li Min, peering in from without,

increased his terror. Like myself, he sprang up and dashed toward the

window, placing his right foot, as I did, upon the low stool beside the

bed. His first dash forward and upward, to a standing position, like my

own, brought his head, elevated by the height of the stool, in contact

with the spike upon the lower end of the chandelier with great force.

The spike entered his head, fracturing the skull. He was a taller and

heavier man than myself, and the force of the contact as he sprang

forward and upward must have been terrific. In my case, owing to my

having jumped from the bed at a slightly different point, I struck the

spike only a glancing blow, which was sufficient however to render me

unconscious for several minutes. I fell to the floor, senseless, but in

a short time I struggled to my knees and managed, by crawling painfully

to the door, to escape from the room. The interval, from the time I

first fell to the time I reached the hall and again became unconscious,

must have been very short."

"Why?" asked McQuade, who, like the others, followed my every word with

intense interest.

"Because, had the time been very long, I, like Mr. Ashton, should never

have risen at all. You would have found me here this morning, as he was

found."

"But why?" asked Major Temple.

For answer I took a box of wax tapers from my pocket and lighted one.

"Have you ever heard of the Cave of Dogs, near Naples?" I inquired.

"Carbon dioxide," gasped the Major with a look of comprehension.

Sergeant McQuade looked blank, and I saw that to him neither my question

nor the Major's answer had conveyed any definite meaning. "Look," I

cried, as I held the match out before me, where it burned with a bright,

clear flame.

McQuade's mystification increased. I think he wondered if I were trying

to play some practical joke upon him. But, when I slowly lowered the

taper until it reached a point a few inches above my knee, and its

flame faded away and then suddenly went out, as though the match had

been plunged into a basin of water, his expression slowly cleared, and

he gave a significant grunt. "Carbonic-acid gas," he said. "I

understand. But where does it come from?"

"That I do not know, at the moment," I said, "but I think there should

be no great difficulty in finding out. This room has been closed for a

long time. Even when Mr. Ashton came here, it was opened for only a few

moments. Neither he nor I opened the windows, because of the rain, as

you know. Somehow, just how I cannot say, a slow stream of carbonic-acid

gas finds its way into this room. It is the product of combustion, as

you of course know, and is produced in large quantities by burning coal.

It may come through the register from the furnace, or from some peculiar

action of partially slacked lime in the plaster of the walls. Wherever

it comes from, being heavier than air, it slowly settles to the floor,

where it collects, becoming deeper and deeper, just as water collects

and rises in a tank. Look." I tore a few sheets from the magazine I had

been reading the night before, which still lay upon the bed, and

lighting them with another match, extinguished the flame, but allowed

the smoke from the smoldering paper to spread about the room. It slowly

sank until it rested upon the surface of the heavy gas, like a layer of

ice upon the surface of a body of water. It showed the carbon dioxide to

be considerably over two feet deep, and some six or eight inches below

the level of the top of the bed. I knew it must have risen higher during

the night, as it was its deadly fumes, closing about my pillow and

beginning to enter my lungs, that caused my troubled dreams, as well as,

ultimately, the feeling of suffocation which had caused me to awake so

suddenly. A considerable portion of the gas had evidently flowed out

through the open door, as I lay across the threshold, after my escape

from the room.

"And that is what killed poor Boris," said the Major, as he watched the

eddying whirls of smoke which settled and rested upon the surface of the

gas. "Exactly," I said, "and probably Ashton as well. His skull was

fractured, it is true, but the divisional surgeon at the inquest

reported, you may remember, that the fracture was not sufficient of

itself to have caused instant death. It was ten minutes or more, I

should say, from the time I was first awakened by Ashton's cry, until we

finally broke in the door and reached his side. By that time he had

suffocated. The gas, as no doubt you know, is not a poisonous one, but

containing no oxygen which the lungs can take up, acts very much the

same as water would if breathed into the lungs."

Muriel looked at me with admiring eyes. I did not tell her that my

father had intended me to be, like himself, an engineer, and that I had

taken a pretty thorough technical course before adopting art as a

profession. And, after all, the simple explanations I had made were

known to almost every schoolboy with a little knowledge of chemistry or

physics.

"I believe your explanation of Mr. Ashton's death is the correct one,

Mr. Morgan," said McQuade, and he said it ungrudgingly. "But how, after

all, did the missing emerald come to be found in the cake of soap?"

"Undoubtedly Ashton put it there," I replied. "He realized the enormous

value of the thing and feared that some attempt might be made to take it

from him. His hiding place for the jewel was certainly an ingenious one,

and you will remember that you and your men searched the room thoroughly

on more than one occasion without finding it."

McQuade looked a bit sheepish at this. He walked over to the chandelier

and examined its ugly-looking spike with deep interest. It was stained

with dried blood and a few bits of hair still clung to it, but whether

Ashton's or my own, we could of course not tell. There seemed nothing

further that we could do, and, as McQuade said he intended going into

Exeter immediately after luncheon to make his report, and have the

authorities make an examination into the cause of the collection of the

carbonic-acid gas in the room, as well as the stains of blood, etc.,

upon the point of the chandelier, I suggested that I accompany him, as I

wanted to get my wound dressed without delay.

We set out, about an hour later, with Gibson and the high cart, and on

the way McQuade told me about his attempts to locate the much sought

emerald. It seems that after two days of effort his men had located the

underground temple of Buddha, but, when they found it, it had been

stripped of all its decorations and was merely an old cellar floored

over. It appears that the Chinamen, in taking us from the house in

Kingsgate street, had passed through an areaway back of the house, and

thence through a gateway in the rear wall, into a narrow court, along

which they had proceeded some distance. From here they had entered the

rear of a house facing upon the adjoining street, to which the cellar

belonged. The house had been taken, but a short time before, by a couple

of Chinamen who wished to use it as a dwelling. They were seldom seen by

the neighbors, and visitors came and went at night, unnoticed by the

occupants of the neighboring houses. They had all, however, completely

disappeared, and left hardly a trace of their presence. No doubt by now

the emerald Buddha was far on its way toward the little shrine in Ping

Yang, carefully secreted among the belongings of the old temple priest.

I felt a sort of secret satisfaction at learning this, and I think

Sergeant McQuade did as well. Certainly it did not belong in this part

of the world, and its possession could have brought nothing but trouble

and danger to all of us. I think Major Temple was glad, as well,

although I never heard him mention the subject of the jewel again. I

fancy he felt to some extent responsible for Ashton's death, or at least

for having sent him upon the quest which ultimately resulted in it.

I had six stitches taken in my head by an excellent old doctor in town,

who tried his best to find out how I had come by such a severe wound,

but I refused to satisfy his curiosity, and drove back with Gibson an

hour later, after saying good-by to the man from Scotland Yard. He

never, to my knowledge visited The Oaks again, although I received a

letter from him later, with reference to the investigation which the

authorities had made into the cause of the accumulation of the

carbonic-acid gas in the room which Ashton and myself had successively

occupied with such disastrous results. It seems that the heating system

in the house had been installed by its former occupant and owner, a

native of Brazil, unused to our cold English winters. It consisted of a

series of sheet iron pipes, leading from a large furnace in the cellar.

The pipe which supplied the heat for the green room, whether by accident

or design, led directly from the combustion chamber of the furnace

instead of from a hot-air chamber, as was the case with the other pipes.

The consequence was that while the hot air taken to the other rooms was

pure air, drawn from without and heated, that which supplied the green

room carried away from the furnace great quantities of carbon dioxide,

produced in the combustion of the coal. An old valve in the pipe showed

that this source of supply could be shut off when so desired, and from

this I judged that the owner of the house may have had the piping

intentionally so constructed, with the idea of putting out of the way

some undesirable friends or relatives. That such was actually the case

seemed borne out by the rumors of at least two sudden and mysterious

deaths which were known to have occurred in the house. Major Temple,

owing to his long residence in India and the East could not endure a

cold house, and the presence of this heating plant had been one of the

reasons which had governed him in leasing the house for the winter. As

far as I was concerned, I had not noticed the register in the wall at

all, during the night I slept in the room, having forgotten its

existence. I presume it had been turned on by Mr. Ashton. Had I noticed

it, I should certainly have turned it off, as I particularly dislike to

sleep in a heated room.

I reached the house about four o'clock and found Muriel awaiting my

return in the library. Her father, she told me, had gone off for a

walk. We had a great deal to say to each other, and it took us till

dinner to say it, but I have an idea that it would not interest the

reader particularly. We had a lively party at dinner, and the Major got

out some special vintage champagne to celebrate our engagement and drink

to our future happiness. It was late before I turned in, and I did not,

you may be sure, sleep in the green room. The next day, I set out for

Torquay by rail, to explain to my mother my long delay in arriving, and

to tell her about Muriel. With my departure from The Oaks the story of

the emerald Buddha, and the memorable week it caused me, is ended, but

the blessings that came to me through it I had only begun to appreciate.

I have not become a Buddhist, yet I confess that I never see a statue of

that deity but I bend my head before his benign and inscrutable face,

and render up thanks for the great blessings he has showered upon me. It

has now been three years since Muriel and I were married, and they have

been three years of almost perfect happiness. We think of making a trip

to China, some of these days, and, if we do, we have concluded to make a

special pilgrimage to Ping Yang, and place upon the altar of Buddha the

most beautiful bunch of flowers that money can buy, as a little offering

and testimonial of our appreciation of what he has done for us.
