“By the way, you were right about the colours of those beads, and also about the way they were used.”

“As to their use, that was a mere guess; but it has turned out to be correct. It was well that we found the beads, for, small as is the amount of information they give, it is still enough to carry us a stage further.”

“How so?”

“I mean that the cabman’s evidence tells us only that this woman entered the house. The beads tell us that she was in the bedroom; which, as you say, seems to connect her to some extent with Jeffrey’s death. Not necessarily, of course. It is only a suggestion; but a rather strong suggestion under the peculiar circumstances.”

“Even so,” said I, “this new fact seems to me so far from clearing up the mystery, only to add to it a fresh element of still deeper mystery. The porter’s evidence at the inquest could leave no doubt that Jeffrey contemplated suicide, and his preparations pointedly suggest this particular night as the time selected by him for doing away with himself. Is not that so?”
