"Do many people come down here in the course of an evening?" Dorrington asked.
"Never anybody but myself."
"Very well. Stand away at your side door."
"DORRINGTON, WITH THE LANTERN, EXPLORED THE MUDDY COBBLE STONES."
Bouvier and his wife stood huddled and staring on the threshold of the side door, while Dorrington, with the lantern, explored the muddy cobble stones. The pieces of a broken bottle lay in a little heap, and a cork lay a yard away from them. Dorrington smelt the cork, and then collected together the broken glass (there were but four or five pieces) from the little heap. Another piece of glass lay by itself a little way off, and this also Dorrington took up, scrutinising it narrowly. Then he traversed the whole passage carefully, stepping from bare stone to bare stone, and skimming the ground with the lantern. The mud lay confused and trackless in most places, though the place where Bouvier had been lying was indicated by an appearance of sweeping, caused, no doubt, by his wife dragging him to his feet. Only one other thing beside the glass and cork did Dorrington carry away as evidence, and that the Bouviers knew nothing of; for it was the remembrance of the mark of a sharp, small boot-heel in more than one patch of mud between the stones.
"Will you object, Madame Bouvier," he asked, as he handed back the lantern, "to show me the shoes you wore when you found your husband lying out here?"
Madame Bouvier had no objection at all. They were what she was then wearing, and had worn all day. She lifted her foot and exhibited one. There was no need for a second glance. It was a loose easy cashmere boot, with spring sides and heels cut down flat for indoor comfort.
"And this was at what time?"
It was between seven and eight o'clock, both agreed, though they differed a little as to the exact time. Bouvier had recovered when his wife raised him, had entered the house with her, at once discovered his loss, and immediately, on his wife's advice, set out to find Dorrington, whose name the woman had heard spoken of frequently among the visitors to the café in connection with the affair of the secret society already alluded to. He had felt certain that Dorrington would not be at his office, but trusted to be directed where to find him.
