"On. the contrary," said Morgan, "it would be taking no chance at all. That man has been wanted for a year for putting over a confidence game. I won't mention any names because lips sometimes tell stories to watchful eyes. You just sit here and you'll see something in a few minutes." With that, Morgan went out.

A few minutes later a man strolled through the lobby and approached the stranger. He leaned over and whispered to him and the two went out together. Marsh was congratulating himself that when this man got to Headquarters he might be made to talk to some effect, when Morgan and another man, whom Marsh easily recognized as a detective, approached.

"Where in blazes did your man go?" exclaimed Morgan.

Marsh stared for a moment. "Why I thought your man got him," he said. "Somebody came in and quietly took him out."

"Good-night!" exclaimed Morgan. "Somebody must have tipped him off."

He turned to the man with him. "No use hanging around now. Our bird's flown."

As the man left them Morgan sat down again beside Marsh. "How the deuce did you know I was here?" he asked.

"I didn't," returned Marsh. "I had that bell boy page you to test the man across from me. I never had such a surprise in my life as when you turned up. What were you doing here?" he added.

"The Chief asked me to look into this Merton case. What were YOU doing here?"

"The same thing," replied Marsh.

"Looking up Merton?"

"Yes."

"Well, that's funny. What for?"

"Because I strongly suspect he is the murdered man in our case."

Morgan gasped.

CHAPTER XIV

THE NIGHT CALL

As Morgan recovered from his astonishment, Marsh antic.i.p.ated some leading questions. He headed these off at this time, by saying, "In this case, conditions seem to be somewhat reversed; for up to this time we have found practically no one who could be put under surveillance, yet we have every evidence that we are being carefully watched by others. Several incidents have occurred, including the present little drama which convinces us of that fact. There is no question that we should again compare notes as soon as possible, but this is a dangerous place to discuss the case. I came here to question certain people. As they will not be on duty until later there is nothing I can do along that line for a little while. In the meantime, we ought to look over Merton's rooms upstairs. I could not make an attempt to do this, because I do not possess the proper authority without explaining my real connections. You, however, as a city detective engaged on the case, will have no difficulty in making arrangements to inspect his room."

"That is just what I dropped in to do," replied Morgan.

"Then go ahead and make your arrangements," said Marsh, "and when you are ready, let me go up with you. If we meet anyone, remember that I am working under the special authorization of Mr. Hunt, and you and I have just become acquainted."

Morgan went to the hotel office. In a few minutes he returned with a bell boy and nodded to Marsh. Guided by the bell boy, they took an elevator and ascended to Merton's rooms, which they found consisted of a sitting room, bedroom and bath. Obeying instructions, the bell boy at once retired and closed the door after him.

They first inspected the bedroom, giving special attention to the dresser. This contained nothing save the usual supply of clothing, which served no other purpose than to indicate the wealth and conservative taste of the owner. Marsh particularly sought some jewelry that might help to identify the cuff b.u.t.ton as the property of the lost man. He found nothing, however, and considered it probable that whatever jewelry Merton owned was on his person.

From the bedroom the two men went to the sitting room, which they hoped would hold greater possibilities, for a desk stood in one corner near a window. A framed photograph of Merton's wife and son, standing on top of the desk, of course had no significance. They then began a search of the drawers and the interior of the desk.

"Probably you have noticed," said Marsh, after a moment, "the disordered condition of this desk."

"Now that you speak of it," agreed Morgan, "I think it is pretty well mussed up."

"I should say," commented Marsh, "that either Merton is very careless, or else we are not the first people to examine this desk."

"Probably the desk has been gone over, Marsh," acceded Morgan. "But you must remember that Merton has been known to be missing for several days and hotel employees, even under ordinary circ.u.mstances, are apt to be curious. The point is worth remembering, but I doubt if it is of any importance."

One by one, they examined various letters and papers. A few touched on business subjects, but the majority were of a personal nature.

Most of these were from Merton's wife; the others from business men whose well known names placed them beyond suspicion. In one corner of the desk Morgan picked up a sheet containing some notations regarding bond purchases. Beneath this he found a black, leather-covered notebook of a size that would conveniently fit into a vest pocket. One glance into this and Morgan gave an exclamation. "See here!" he cried, calling Marsh's attention to the book. "This notebook has been kept in cipher. These combinations of letters and figures mean absolutely nothing as they stand."

The two men slowly turned the pages, but as Morgan had stated, the matter which the book contained conveyed nothing to them.

"That looks as if Merton had something to conceal, Marsh."

"On the face of it--yes," returned Marsh. "But just glance at this sheet which covered the notebook. From its subject matter I should be inclined to believe that it represented Merton's handwriting."

Morgan nodded and Marsh went on.

"Now, when you come to look at this notebook, even a hasty glance shows a difference in the handwriting. In. fact, now that my attention has been drawn to it, there is really a marked difference."

"Well?" queried Morgan.

"Offhand," returned Marsh, "I would say, that somebody has been keeping a secret record. That person sat at this desk making additional notes. In a moment of forgetfulness, or perhaps the necessity of hasty concealment, the notebook was placed under this sheet and later overlooked. There is a possibility that this notebook was left by the person who preceded us at this desk."

Morgan took the notebook and examined it carefully for a few minutes. "In my work," he said, "I have several times run up against ciphers of various kinds. This is unlike anything I ever saw before, and looks as if it would be mighty hard to unravel."

Marsh again took the book and after carefully examining it, said, "I don't pretend to be a cipher expert. In fact, I never waste time on it. We have men both here and at Washington who can read this sort of stuff backward. I'll send this book to them and we'll soon get a key to the cipher."

At this moment, both men became silent and alert. Someone was slipping a key into the lock of the door. Marsh quickly dropped the notebook into the side pocket of his coat. A moment later the door swung open and Gilbert Hunt entered.

He stopped with a start of surprise, but quickly recovered himself.

"You gentlemen gave me a shock!" he exclaimed. "I didn't expect to find anyone here. Already on the job, Mr. Marsh?" he added.

"Yes," returned Marsh, easily. "I never lose any time, and this room naturally should be looked over."

"And this gentleman with you?" questioned Hunt.

"Detective Sergeant Morgan--Mr. Hunt," introduced Marsh. "Morgan is conducting the police investigation." Then he added, with a wink at Hunt. "We met downstairs and I thought we might as well look things over at the same time."

"I see," said Hunt, smiling. "Have you discovered anything?"

"Nothing to which I can attach any great importance at this time,"

replied Marsh.

"I thought I would come up and look things over," explained Hunt, as he strolled over to the desk and ran his fingers through the papers.

The two men watched him with keen attention.

"Seems to be nothing here outside of personal correspondence," said Hunt, turning around.
