The light of morning appeared to have instilled rather more courage into Mr. Copperdock’s heart. He announced his determination to carry on business as usual, but insisted that Inspector Whyland should be communicated with and told of his discovery of the numbered counter. It was about ten o’clock when Whyland arrived in Praed Street, but instead of going straight to Copperdock’s shop, he went first to the herbalist’s.
“What’s this story about Copperdock having found a numbered counter?” he asked, as soon as they were safely hidden in the back room from prying ears.
Mr. Ludgrove recounted his experiences of the past night, and as he came to a conclusion Whyland laughed contemptuously. “Is this another of Copperdock’s hallucinations, like that meeting of his with the black sailor?” he enquired.
“Not altogether,” replied Mr. Ludgrove with a smile. “The counter is real enough, at all events. He left it here last night. Here it is.”
Whyland examined the counter in silence. He had very little doubt that Mr. Copperdock had staged the whole affair, had written the figure VI upon it in red ink himself, and had placed it on his bed. But why? What was his game? Was this a feeble scheme to draw suspicion from himself? The series of murders appeared to have come to an end. What was the point of reviving the memory of them like this?
Mr. Ludgrove broke in upon his meditations. “I took the liberty of examining it under a powerful glass,” he said, nodding his head towards the bench. “It seems to be an ordinary bone counter and the figure VI has been drawn upon it with a steel pen and red ink.”
“Just as the others were,” agreed Whyland. “I’ll keep this counter, if you don’t mind. I want to add it to my collection. Now I suppose I had better step across and see Copperdock. I should like you to come with me, if you can spare the time.”
“I think I can risk shutting the shop for a few minutes,” replied the herbalist. “I get very few customers in the morning. Most of the people who require my services are at work all day.”
“Dishonest work, I’ll be bound,” said Whyland chaffingly. “Well, come along, then.”
They went across to Mr. Copperdock’s shop together, and were shown by the tobacconist into the room behind the shop, which was used as an office. At one side was a table upon which stood a Planet typewriter, at the other a desk. Inspector Whyland seated himself at the latter, selected one of the pens before him, and dipped it into an inkpot, which happened to contain red ink.
