"Well, I did come over, and I saw him in this very room where we are sitting. He was cheerful as usual, and even joked me on the possibility that I might at last uncover one of the insidious enemies to health that so often make their appearance in middle life. But there was nothing, absolutely nothing—heart, lungs, circulatory system—all in first-class shape. As a matter of form, there would have to be a laboratory analysis, but otherwise I was prepared to give him a clean bill of health, and I told him so. He took it quite as a matter of course, and, after arranging for a round of golf that same afternoon at the Lost River Country Club, we parted. That was around ten o'clock, and at half past two I had a telephone from the 'Hundred,' asking me to come over at once. When I arrived I was taken in here. Graeme lay on the floor, alongside the big library table. On his right temple there was a noticeable contusion, triangular in shape. He was stone dead."
"Could you tell how long?"
"Probably a couple of hours."
"The wound, of course, was your first thought."
"Naturally. And in itself it was quite enough to have caused death. Remember that it was on the temple, a vulnerable spot."
"An assailant then?"
"By hypothesis certainly. I may say that I have had some experience in criminal cases; accordingly I was very careful not to disturb anything, and up to this time I had only touched the man's wrist to assure myself that the pulse was gone."
"Who was it that gave the alarm?"
"I am told that one of the servants, Effingham, to be precise, knocked on the library door at about half past one o'clock, to announce the serving of luncheon. He then went away without waiting for an answer from Mr. Graeme; it seems that was his custom on the occasion of this particular summons. A half hour later, when Mr. Graeme failed to appear at the table, Miss Trevor told Effingham to go again and make sure that his master had heard the message. I understood that occasionally Graeme would not come to luncheon, especially if he happened to be more than usually busy; he might appear an hour or so later, and forage around for a glass of milk and a couple of biscuits."
"His tardiness then excited no surprise?"
