no communicating doors, and altogether the room is planned to stand a siege."

The Chief Commissioner was interested.

"Any more?" he asked.

"Let me think," said T. X., looking up at the ceiling. "Yes, the interior of his room is plainly furnished, there is a big fireplace, rather an ornate bed, a steel safe built into the wall and visible from its outer side to the policeman whose beat is in that neighborhood."

"How do you know all this?" asked the Chief Commissioner.

"Because I've been in the room," said T. X. simply, "having by an underhand trick succeeded in gaining the misplaced confidence of Kara's housekeeper, who by the way"—he turned round to his desk and scribbled a name on the blotting-pad—"will be discharged to-morrow and must be found a place."

"Is there any—er—?" began the Chief.

"Funny business?" interrupted T. X., "not a bit. House and man are quite normal save for these eccentricities. He has announced his intention of spending three months of the year in England and nine months abroad. He is very rich, has no relations, and has a passion for power."

"Then he'll be hung," said the Chief, rising.

"I doubt it," said the other, "people with lots of money seldom get hung. You only get hung for wanting money."

"Then you're in some danger, T. X.," smiled the Chief, "for according to my account you're always more or less broke."

"A genial libel," said T. X., "but talking about people being broke, I saw John Lexman to-day—you know him!"

The Chief Commissioner nodded.

"I've an idea he's rather hit for money. He was in that Roumanian gold swindle, and by his general gloom, which only comes to a man when he's in love (and he can't possibly be in love since he's married) or when he's in debt, I fear that he is still feeling the effect of that rosy adventure."

A telephone bell in the corner of the room rang sharply, and T. X. picked up the receiver. He listened intently.

"A trunk call," he said over his shoulder to the departing commissioner, "it may be something interesting."

A little pause; then a hoarse voice spoke to him. "Is that you, T. X.?"

"That's me," said the Assistant Commissioner, commonly.

"It's John Lexman speaking."

"I shouldn't have recognized your voice," said T. X., "what is wrong with you, John, can't you get your plot to went?"

"I want you to come down here at once," said the voice urgently, and even over the telephone T. X. recognized the distress. "I have shot a man, killed him!"

T. X. gasped.

"Good Lord," he said, "you are a silly ass!"
