CHAPTER XIII

/At/ the last moment the bank authorities had changed their mind, and

overnight had sent £53,000 worth of gold for conveyance to the ship.

They had borrowed for the purpose an army lorry from Woolwich, a

service which is sometimes claimed by the national banking

institution.

The lorry had been accompanied by eight detectives, the military

driver being also armed. Tilbury was reached at half-past eleven

o’clock at night, and the lorry, a high-powered Lassavar, had returned

to London at two o’clock in the morning and had been loaded in the

bank courtyard under the eyes of the officer, sergeant, and two men of

the guard which is on duty on the bank premises from sunset to

sunrise. A new detachment of picked men from Scotland Yard, each

carrying an automatic pistol, loaded the lorry for its second journey,

the amount of gold this time being £73,000 worth. After the boxes had

been put into the van, they had climbed up and the lorry had driven

away from the bank. Each of the eight men guarding this treasure was

passed under review by a high officer of Scotland Yard who knew every

one personally. The lorry was seen in Commercial Road by a

detective-inspector of the division, and its progress was also noted

by a police-cyclist patrol who was on duty at the junction of the

Ripple and Barking roads.

The main Tilbury road runs within a few hundred yards of the village

of Rainham, and it was at this point, only a few miles distant from

Tilbury, that the lorry disappeared. Two motor-cyclist policemen who

had gone out to meet the gold-convoy, and who had received a telephone

message from the Ripple road to say that it had passed, grew uneasy

and telephoned to Tilbury.

It was an airless morning, with occasional banks of mist lying in the

hollows, and part of the road, especially near the river, was patchily

covered with white fog, which dispersed about eight o’clock in the

morning under a southeasterly wind. The mist had almost disappeared

when the search party from Tilbury pursued their investigations and

came upon the one evidence of tragedy which the morning was to reveal.

This was an old Ford motor car that had evidently run from the road,

miraculously missed a telegraph pole, and ditched itself. The machine

had not overturned; there were no visible marks of injury; yet the man

who sat at the wheel was stone dead when he was found. An immediate

medical examination failed to discover an injury of any kind to the

man, who was a small farmer of Rainham, and on the face of it it

looked as though he had died of a heart attack whilst on his way to

town.

Just beyond the place where he was found the road dips steeply between

high banks. It is known as Coles Hollow, and at its deepest part the

cutting is crossed by a single-track bridge which connects two

portions of the farm through which the road runs. The dead farmer and

his machine had been removed when Reeder and the chief of Scotland

Yard arrived on the spot. No news of any kind had been received of the

lorry; but the local police, who had been following its tracks, had

made two discoveries. Apparently, going through the cutting, the front

wheels of the trolley had collided with the side, for there was a deep

scoop in the clayey soil which the impact had hollowed out.

“It almost appears,” said Simpson, who had been put in charge of the

case, “that the trolley swerved here to avoid the farmer’s car. There

are his wheel tracks, and you notice they were wobbling from side to

side. Probably the man was already dying.”

“Have you traced the trolley tracks from here?” asked Reeder.

Simpson nodded, and called a sergeant of the Essex Constabulary, who

had charted the tracks.

“They seem to have turned up north towards Becontree,” he said. “As a

matter of fact, a policeman at Becontree said he saw a large trolley

come out of the mist and pass him, but that had a tilt on it and was

going towards London. It was an army trolley, too, and was driven by a

soldier.”

Mr. Reeder had lit a cigarette and was holding the flaming match in

his hand, staring at it solemnly.

“Dear me!” he said, and dropped the match and watched it extinguish.

And then he began what seemed to be a foolish search of the ground,

striking match after match.

“Isn’t there light enough for you, Mr. Reeder?” asked Simpson

irritably.

The detective straightened his back and smiled. Only for a second was

he amused, and then his long face went longer than ever.

“Poor fellow!” he said softly. “Poor fellow!”

“Who are you talking about?” demanded Simpson, but Mr. Reeder did not

reply. Instead, he pointed up to the bridge, in the centre of which

was an old and rusted water-wagon, the type which certain English

municipalities still use. He climbed up to the bank and examined the

iron tank, opened the hatches and groped inside, lighting matches to

aid his examination.

“Is it empty?” asked Simpson.

“I am afraid it is,” said Mr. Reeder, and inspected the worn hose

leading from its iron spindles. He descended the cutting more

melancholy than ever.

“Have you thought how easy it is to disguise an ordinary army lorry?”

he asked. “A tilt, I think the sergeant said, and on its way to

London.”

“Do you think that was the gold-van?”

Mr. Reeder nodded.

“I’m certain,” he said.

“Where was it attacked?”

Mr. Reeder pointed to the mark of the wheels on the side of the road.

“There,” he said simply, and Simpson growled impatiently.

“Stuff! Nobody heard a shot fired, and you don’t think our people

would go down without a fight, do you? They could have held their own

against five times their number, and no crowd has been seen on this

road!”

Mr. Reeder nodded.

“Nevertheless, this is where the convoy was attacked and overcome,” he

said. “I think you ought to look for the trolley with the tilt, and

get on to your Becontree man and get a closer description of the

machine he saw.”

In a quarter of an hour the police car brought them to the little

Essex village, and the policeman who had seen the wagon was

interviewed. It was a few minutes before he went off duty, he said.

There was a thick mist at the time, and he heard the rumble of the

lorry wheels before it came into sight. He described it as a typical

army wagon. So far as he could tell, it was grey, and had a black tilt

with “W.D.” and a broad-arrow painted on the side, “W.D.” standing for

War Department, the broad-arrow being the sign of Government. He saw

one soldier driving and another sitting by his side. The back of the

tilt was laced up and he could not see into the interior. The soldier

as he passed had waved his hand in greeting, and the policeman had

thought no more about the matter until the robbery of the gold convoy

was reported.

“Yes, sir,” he said, in answer to Reeder’s inquiry, “I think it was

loaded. It went very heavily on the road. We often get these trolleys

coming up from Shoeburyness.”

Simpson had put through a telephone inquiry to the Barking police, who

had seen the military wagon. But army convoys were no unusual sight in

the region of the docks. Either that or one similar was seen entering

the Blackwall Tunnel, but the Greenwich police, on the south side of

the river, had failed to identify it, and from there on all trace of

the lorry was lost.

“We’re probably chasing a shadow anyway,” said Simpson. “If your

theory is right, Reeder--it can’t be right! They couldn’t have caught

these men of ours so unprepared that somebody didn’t shoot, and

there’s no sign of shooting.”

“There was no shooting,” said Mr. Reeder, shaking his head.

“Then where are the men?” asked Simpson.

“Dead,” said Mr. Reeder quietly.

It was at Scotland Yard, in the presence of an incredulous and

horrified Commissioner, that Mr. J. G. Reeder reconstructed the crime.

“Flack is a chemist: I think I impressed it upon you. Did you notice,

Simpson, on the bridge, across the cutting, was an old water-cart? I

think you have since learnt that it does not belong to the farmer who

owns the land, and that he has never seen it before. It may be

possible to discover where that was purchased. In all probability you

will find that it was bought a few days ago at the sale of some

municipal stores. I noticed in _The Times_ there was an advertisement

of such a sale. Do you realise how easy it would be not only to store

under pressure, but to make, in that tank, large quantities of a

deadly gas, one important element of which is carbon monoxide? Suppose

this, or, as it may prove, a more deadly gas, has been so stored, do

you realise how simple a matter it would be on a still, breathless

morning to throw a big hose over the bridge and fill the hollow with

the gas? That is, I am sure, what happened. Whatever else was used,

there is still carbon monoxide in the cutting, for when I dropped a

match it was immediately extinguished, and every match I burnt near

the ground went out. If the car had run right through and climbed the

other slope of the cutting, the driver and the men inside the trolley

might have escaped death. As it was, rendered momentarily unconscious,

the driver turned his wheel and ran into the bank, stopping the

trolley. They were probably dead before Flack and his associate,

whoever it was, jumped down, wearing gas masks, lifted the driver back

into the trolley and drove on.”

“And the farmer----” began the Commissioner.

“His death probably occurred some time after the trolley had passed.

He also descended into that death hollow, but the speed at which his

car was going carried him up nearer the cutting, though he must have

been dead by the time he got out.”

He rose and stretched himself wearily.

“Now I think I will go and interview Miss Belman and set her mind at

rest,” he said. “Did you send her to the hotel, as I asked you, Mr.

Simpson?”

Simpson stared at him in blank astonishment.

“Miss Belman?” he said. “I haven’t seen Miss Belman!”
