AN ELECTRICAL DETECTIVE

"Orr, Mr. Black wants you."

Jack, who was passing through the business department of the Hammerton

office, toward the stair which led to the operating room, promptly turned

aside and entered the manager's private room.

"Good morning, Jack. Sit down.

"My boy," began the manager, "can you keep a secret?"

"Why yes, sir," responded Jack, wondering.

"Very well. But I must explain first. I suppose you did not know it--we

kept it quiet--but the real reason Hansen, the janitor, was discharged a

month ago was that he was found taking money from the safe here, which he

had in some way learned to open. After he left I changed the safe

combination, and thought the trouble was at an end.

"Last Tuesday morning the cash was again a little short. At the time I

simply thought an error had been made in counting the night before. This

morning a second ten-dollar bill is missing, and the cash-box shows

unmistakable signs of having been tampered with.

"Now Johnson, the counter clerk, to whom I had confided the new

combination (for it is customary, you know, that two shall be able to open

a safe, as a precaution against the combination being forgotten)--Johnson

is entirely above suspicion. Still, to make doubly sure, I am going to

alter the combination once more, and share it with someone outside of the

business department. And as you have impressed me very favorably, I have

chosen you.

"That is, of course," concluded the manager, "if you have no objection."

"Certainly not. I am sure I appreciate the confidence, sir," said Jack

quickly.

"Very well, then. The combination is 'Right twenty, twice; back nine;

right ten.' Can you remember that? For you must not write it down, you

know."

Jack repeated the number several times; and again thanking the manager

for the compliment, continued up-stairs to the telegraph-room.

Two mornings later Jack was again called into Mr. Black's office. For a

moment, while Jack wondered, the manager eyed him strangely, then asked,

"What was that combination, Jack?"

"Right ninety--no, right thirty--Why, I believe I have forgotten it,

sir," declared Jack in confusion.

"Perhaps you have forgotten this too, then?" As he spoke the manager took

from his desk a small notebook. "I found it on the floor in front of the

safe this morning."

"It is mine, sir. I must have dropped it last night. I worked extra until

after midnight, sir," explained Jack, "and on the way out I chased a

mouse in here from the stairway, and when it ran under the safe I dropped

to my knees to find it. The book must have fallen from my pocket.

"But what is wrong, sir?"

"The cash-box is not in the safe this morning."

Jack started back, the color fading from his cheeks as the significance

of it all came to him.

"And now you pretend to have the combination entirely wrong," went on the

manager.

Jack found his voice. "Mr. Black, you are mistaken! You are mistaken! I

never could do such a thing! Never!"

"I would prefer proof," Mr. Black said coldly.

Jack caught at the idea. "Would you let me try to prove it, sir? Will you

give me a week in which to try and clear myself?"

"Well, I did not mean it that way. But, all right--a week. And if things

do not look different by that time, and you still claim ignorance, you

will have to go. That is all there is to it."

"Thank you, sir."

At the door Jack turned back. "Mr. Black, you are positive you returned

the box to the safe?"

"Positive. It is the last thing I do before going home."

During spare moments on his wire that morning Jack debated the mystery

from every side. Finally he had boiled it down to two conflicting facts:

"First: That the box was placed in the safe the night before, and in the

morning was gone; and that, besides the manager, he was the only one who

could have opened the safe and taken it. And,

"Second: That, of course, he knew his own innocence."

The only alternative, then, was that Mr. Black had been mistaken in

thinking he had returned the box to the safe.

Grasping at this possibility, Jack argued on. How could the manager have

been mistaken? Overlooked the box, say because of its being covered by

something?

"Why it may be there yet!" exclaimed Jack hopefully. And a few minutes

later, relieved from his wire for lunch, he hurriedly descended again to

the manager's office.

"Mr. Black, may I look around here a bit?" he requested.

"Look around? What for?"

"To see if I cannot find something to help solve this mystery," responded

Jack, not wishing directly to suggest that the manager had overlooked the

box.

"So you keep to it that you know nothing, eh? Well, go ahead," said the

manager shortly, turning back to his desk.

Jack's hopes were quickly shattered. Neither on the desk, nor a table

beside the safe, was there anything which could have concealed the

missing box.

Stooping, he glanced under the table. Something white, a newspaper,

leaning against the wall, caught his eye. With a flutter of hope he

reached beneath and threw it aside. There was nothing behind it.

Disappointedly he caught the newspaper up and tossed it into the

waste-basket. Suddenly, on a thought, he recovered the paper, and opened

it. On discovering it was the "Bulletin," a paper he knew Mr. Black

seldom read, the idea took definite shape. And, yes, it was of

yesterday's date!

"Mr. Black," exclaimed Jack, "this is not your paper, is it?"
