“Interesting!” grumbled the Inspector. “Aye, the reporters will find it interesting enough, you may bet. We couldn’t keep it dark, even if we wanted to. This fellow Pargent got it by post on Saturday morning. He told his sister, Miss Clara, that it must be a secret token from some admirer of his work. He was so pleased about it that he took it down to Penderworth to show his other sister. It was on his way back from there that he was killed. Oh yes, it’s interesting enough. We shall have to say that Tovey and Colburn got counters like this, and then there’ll be a fearful outcry against us for keeping it dark. ‘Had the police not displayed this criminal reticence, the victim would have understood the purport of the warning and adequate measures could have been taken to protect him.’ Oh yes, I know what’s coming all right.” Inspector Whyland gazed savagely at the counter for a few seconds, then continued abruptly. “Fortunately the envelope in which this one came had been kept. The counter was wrapped up in a piece of cheap writing paper, and put in a square envelope of the same quality. The address was typewritten. Our people at the Yard are trying to trace the machine it was done with. I wish them joy of the job. They can tell the make all right; but there must be thousands of them scattered through London.” “If you don’t mind my suggesting it, it doesn’t follow that because Mr. Pargent received a counter he was murdered by the same hand that killed Mr. Tovey or Mr. Colburn,” said the herbalist quietly. Inspector Whyland glanced at him quickly. “No, it doesn’t exactly follow,” he agreed. “But we’ll return to that later. I want to show you something else first. Look here.” This time he produced from his pocket a paper packet, which he proceeded to unroll. From it he withdrew two sinister-looking blades, each stained a dull brown. “These are the knives with which Tovey and Pargent were killed,” he said. “Don’t touch them, but tell me if you can tell one from the other.” Mr. Ludgrove adjusted his spectacles, and bent over the knives. They were exactly similar, thin, with an extremely sharp point, about half an inch wide and eight inches long. Neither of them showed any sign of having ever possessed a handle. “No, I can see no difference between them,” agreed Mr. Ludgrove. “I admit that they strengthen the supposition that Mr. Tovey and Mr. Pargent died by the same hand. But, admitting that this was the case, it only bears out my theory that the murders were the actions of a maniac. If they were not, if both men were killed with some definite motive, you have to discover some connection between them. Yet they moved in entirely distinct orbits, and, I should imagine, had nothing whatever in common.”
