“Regrets will not bring the poor fellow to life again,” I said with a sigh. “We must act, and act promptly, in order to discover the identity of the murderer and the motive of the crime. That there is a motive is certain; yet it is indeed strange that anyone should actually kill a man suffering from a disease which, in a few months at most, must prove fatal. The motive was therefore his immediate decease, and that fact will probably greatly assist the police in their investigations.”

“But who could have killed him?”

“Ah! that’s the mystery. If, as you believe, the house was found to be still secured when the alarm was raised, then it would appear that someone who slept beneath this roof was guilty.”

“Oh! Impossible! Remember there are only myself and the servants. You surely don’t suspect either of them?”

“I have no suspicion of anyone at present,” I answered. “Let the police search the place, and they may discover something which will furnish them with a clue.”

I noticed some telegraph-forms in the stationery rack on a small writing-table, and taking one scribbled a couple of lines to Sir Bernard, at Hove, informing him of the mysterious affair. This I folded and placed in my pocket in readiness for the re-opening of the telegraph office at eight o’clock.

Shortly afterwards we heard the wheels of the cab outside, and a few minutes later were joined by a police inspector in uniform and an officer in plain clothes.

In a few brief sentences I explained to them the tragic circumstances, and then led them upstairs to the dead man’s room.

After a cursory glance around, they went forth again out upon the landing in order to await the arrival of two other plain-clothes officers who had come round on foot, one of them the sergeant of the Criminal Investigation Department attached to the Kew station. Then, after giving orders to the constable on the beat to station himself at the door and allow no one to enter or leave without permission, the three detectives and the inspector entered the room where the dead man lay.
