He nodded with a kind of satisfaction, and said: "I've wired for a detective; he's more at home at this kind of case than I am." He turned from the safe and examined the part of the floor on which the Marquess had fallen; then he caught sight of the poker and pursed his lips.
"That's what did it," he said, confidently.

"The blood's still wet on it." Heyton made as if to pick up the poker, but the Inspector caught his arm and stayed him.
"Beg pardon, my lord," he said, apologetically.

"But you mustn't touch anything.

We'll let everything bide as it is until the detective comes down from Scotland Yard." He went to the window and examined it; but without touching it.
"Closed and hasped! Have you any idea how they got in, my lord; have any of the servants found a window or a door open ?" "No," replied Heyton; then he added, as if he had suddenly remembered.
"Here, by George, that's strange! I mean about the window.

I found one of the back windows open when I went down this morning for a swim." "Oh!" said the Inspector.
