"Well, no. But I thought the Kennington case would have to wait its turn. And I had no idea that you were in possession of enough facts to enable you to get any farther with it."
"But you knew all the very striking facts of the case, and you saw the further evidence that we extracted from the empty house."
"Do you mean those things that we picked out from the rubbish under the grate?"
"Yes. You saw those curious little pieces of reed and the pair of spectacles. They are lying in the top drawer of that cabinet at this moment, and I should recommend you to have another look at them. To me they are most instructive. The pieces of reed offered an extremely valuable suggestion, and the spectacles enabled me to test that suggestion and turn it into actual information."
"Unfortunately," said I, "the pieces of reed convey nothing to me. I don't know what they are or of what they have formed a part."
"I think," he replied, "that if you examine them with due consideration, you will find their use pretty obvious. Have a good look at them and the spectacles too. Think over all that you know of that mysterious group of people who lived in that house, and see if you cannot form some coherent theory of their actions. Think, also, if we have not some information in our possession by which we might be able to identify some of them, and infer the identity of the others. You will have a quiet day, as I shall not be home until the evening; set yourself this task. I assure you that you have the material for identifying—or rather for testing the identity of—at least one of those persons. Go over your material systematically, and let me know in the evening what further investigations you would propose."
"Very well," said I. "It shall be done according to your word. I will addle my brain afresh with the affair of Mr. Weiss and his patient, and let the Blackmore case rip."
"There is no need to do that. You have a whole day before you. An hour's really close consideration of the Kennington case ought to show you what your next move should be, and then you could devote yourself to the consideration of Jeffrey Blackmore's will."
With this final piece of advice, Thorndyke collected the papers for his day's work, and, having deposited them in his brief bag, took his departure, leaving me to my meditations.
