"You think me foolish, I know, that I persist," she said, "but I do beg that you will remember what I say. Do not be alone to-day more than you can help. Suspect every one who comes near to you. There may be a trap before your feet at any moment. Be wary always and do not forget--at five o'clock I expect you."

Laverick smiled as he bowed his adieux.

"It is a promise, Mademoiselle," he a.s.sured her.

CHAPTER XXVII

PENETRATING A MYSTERY

About an hour after Mademoiselle Idiale's departure a note marked "Urgent" was brought in and handed to Laverick. He tore it open.

It was dated from the address of a firm of stockbrokers, with two of the partners of which he was on friendly terms. It ran thus:

MY DEAR LAVERICK,--I want a chat with you, if you can spare five minutes at lunch time. Come to Lyons' a little earlier than usual, if you don't mind,--say at a quarter to one.

J. HENSHAW.

Laverick read the typewritten note carelessly enough at first. He had even laid it down and glanced at the clock, with the intention of starting out, when a thought struck him. He took it up and read it though again. Then he turned to the telephone.

"Put me on to the office of Henshaw & Allen. I want to speak to Mr.

Henshaw particularly."

Two minutes pa.s.sed. Laverick, meanwhile, had been washing his hands ready to go out. Then the telephone bell rang. He took up the receiver.

"Hullo! Is that Henshaw?"

"I'm Henshaw," was the answer. "That's Laverick, isn't it? How are you, old fellow?"

"I'm all right," Laverick replied. "What is it that you want to see me about?"

"Nothing particular that I know of. Who told you that I wanted to?"

Laverick, who had been standing with the instrument in his hand, sat down in his chair.

"Look here," he said, "Didn't you send me a note a few minutes ago, asking me to come out to lunch at a quarter to one and meet you at Lyons'?"

Henshaw's laugh was sufficient response.

"Delighted to lunch with you there or anywhere, old chap,--you know that," was the answer, "but some one's been putting up a practical joke on you."

"You did not send me a note round this morning, then?" Laverick insisted.

"I'll swear I didn't," came the reply. "Do you seriously mean that you've had one purporting to come from me?"

Laverick pulled himself together.

"Well, the signature's such a scrawl," he said, "that no one could tell what the name really was. I guessed at you but I seem to have guessed wrong. Good-bye!"

He set down the receiver and rang off to escape further questioning.

Now indeed the plot was commencing to thicken. This was a deliberate effort on the part of some one to secure his absence from his offices at a quarter to one.

With the doc.u.ment in his pocket and the safe securely locked, Laverick felt at ease as to the result of any attempted burglary of his premises. At the same time his curiosity was excited. Here, perhaps, was a chance of finding some clue to this impenetrable mystery.

There were thee clerks in the outer office. He put on his hat and despatched two of them on errands in different directions. The last he was obliged to take into his confidence.

"Halsey," he said, "I am going out to lunch. At least, I wish it to be thought that I am going out to lunch. As a matter of fact, I shall return in about ten minutes by the back way. I do not wish you, however, to know this. I want you to have it in your mind that I have gone to lunch and shall not be back until a quarter past two. If there are visitors for me--Inquirers of any sort--act exactly as you would have done if you really believed that I was not in the building."

Halsey appeared a good deal mystified. Laverick took him even further into his confidence.

"To tell you the truth, Halsey," he said, "I have just received a bogus letter from Mr. Henshaw, asking me to lunch with him. Some one was evidently anxious to get me out of my office for an hour or so. I want to find out for myself what this means, if possible.

You understand?"

"I think so, sir," the man replied doubtfully. "I am not to be aware that you have returned, then?"

"Certainly not," Laverick answered. "Please be quite clear about that. If you hear any commotion in the office, you can come in, but do not send for the police unless I tell you to. I wish to look into this affair for myself."

Halsey, who had started life as a lawyer's clerk, and was distinctly formal in his ideas, was a little shocked.

"Would it not be better, sir," he suggested, "for me to communicate with the police in the first case? If this should really turn out to be an attempt at burglary, it would surely be best to leave the matter to them."

Laverick frowned.

"For certain reasons, Halsey, which I do not think it necessary to tell you, I have a strong desire to investigate this matter personally. Please do exactly as I say."

He left the office and strolled up the street in the direction of the restaurant which he chiefly frequented. He reached it in a moment or two, but left it at once by another entrance. Within ten minutes he was back at his office.

"Has any one been, Halsey?"

"No one, sir," the clerk answered.

"You will be so good," Laverick continued, "as to forget that I have returned."

He pa.s.sed on quickly into his own room and made his way into the small closet where he kept his coat and washed his hands. He had scarcely been there a minute when he heard voices in the outside hall. The door of his office was opened.

"Mr. Laverick said nothing about an appointment at this hour," he heard Halsey protest in a somewhat deprecating tone.

"He had, perhaps, forgotten," was the answer, in a totally unfamiliar voice. "At any rate, I am not in a great hurry. The matter is of some importance, however, and I will wait for Mr. Laverick."

The visitor was shown in. Laverick investigated his appearance through a crack in the door. He was a man of medium height, well-dressed, clean-shaven, and wore gold-rimmed spectacles. He made himself comfortable in Laverick's easy-chair, and accepted the paper which Halsey offered him.

"I shall be quite glad of a rest," he remarked genially. "I have been running about all the morning."

"Mr. Laverick is never very long out for lunch, sir," Halsey said.

"I daresay he will not keep you more than a quarter of an hour or twenty minutes."
