“Suppose we try,” Sir Clinton suggested. “Assume that he cut his hand here on the glass. He’d be all asprawl on the floor; and the first thing he’d do would be to put his hands down to help himself up. That would account for these biggish patches here, under the case. Then a foot or so away you see those round marks of droplets with tiny splashes radiating from them with a fair regularity all round. These must have been made by drops falling from his hand while he stood still—no doubt while he was feeling with the other hand for his handkerchief to stanch the bleeding.”
The Inspector indicated his agreement.
“After he’d got it fixed up, one might expect him to go over and look at Foss. He’d gone down on the floor, you remember, while he was hurrying to Foss’s assistance.”
“There’s no sign of that,” Armadale hastened to point out. “I can’t see any blood-drops round about the body.”
“Oh, don’t be in too much of a hurry, Inspector. Perhaps they fell in the pool of Foss’s own blood or, more probably, his handkerchief soaked up any blood that flowed just then.”
Sir Clinton, still with his eyes on the ground, began to cast about in search of further traces.
“Ah, here are a couple of drops at the end of the bay. Have a look at them, Inspector.”
Armadale knelt down and examined the clots.
“Made on his way to the door, probably,” he suggested.
“They might have been, if he was swinging his arms as one does when one walks freely; but one doesn’t usually swing the arm when there’s a fresh wound in the hand, I think. These aren’t round blobs like the others; they’re elongated, and all the splashing from them is at one end—the end towards the safe. His hand, when they were made, was moving towards the safe’s bay, whatever his body was doing.”
