"No. . . . This all happened quite a long time ago. The hands are cold. . . . The murder must have been committed almost immediately after the other . . . as soon as the two men came here by the servants' staircase."

"But the body would have been seen! Think, fifty people must have passed this spot during the last two hours. . . ."

"The body was not here."

"Then where was it?"

"Why, how can I tell?" snapped the chief detective. "Do as I'm doing, look for yourself! You can't find things by talking."

He furiously patted the knob of his stick with a twitching hand; and he stood there, with his eyes fixed on the body, silent and thoughtful. At last he spoke:

"Monsieur le Commissaire, be so good as to have the victim taken to an empty room. Let them fetch the doctor. Mr. Manager, would you mind opening the doors of all the rooms on this passage for me?"

On the left were three bedrooms and two sitting-rooms, forming an empty suite, which M. Lenormand inspected. On the right were four bedrooms. Two were occupied respectively by a M. Reverdat and an Italian, Baron Giacomini, who were both then out. In the third room they found an elderly English maiden lady still in bed; and, in the fourth, an Englishman who was placidly reading and smoking and who had not been in the least disturbed by the noises in the passage. His name was Major Parbury.

No amount of searching or questioning led to any result. The old maid had heard nothing before the exclamations of the policeman: no noise of a struggle, no cry of pain, no sound of quarreling; and Major Parbury neither.

Moreover, there was no suspicious clue found, no trace of blood, nothing to lead them to suppose that the unfortunate Chapman had been in one of those rooms.
