“You mean whether he was Peeping Tom or t'other?”

“Something of that sort,” the Chief Constable answered. Then, changing the subject, he added: “What bits of information are you going to hunt for next, Inspector?”

Flamborough ran over some points in his mind and cleared his throat before speaking.

“First of all, I want to know what this poison was, where it came from, and how long it takes to act. I expect to get something from the P.M. results, and we can always send some of the organs for analysis.”

Sir Clinton nodded his agreement.

“I think we'll get two people on to that part of the thing independently. Say a London man and perhaps one of the chemists at the Croft-Thornton Institute here. We'll need to see this fellow Markfield in any case, just to check the statements that Ringwood gave us, and when we're doing that we can find out if there's anyone capable of doing the analysis for us. Perhaps Markfield himself might take it on.”

The Inspector, seeing that Sir Clinton was waiting for him to continue, proceeded with his list of evidence required.

“I'll put Yarrow on to the matter of young Hassendean's pistol license. That won't take long to look up, and it will help to clinch the fact that it really was his pistol that we found on the floor. I don't suppose for a moment that it was brought in from the outside. The loose ammunition in the drawer seems convincing on that point.”

“I'm quite with you there,” Sir Clinton admitted.

“Then I want to look into the maid's affairs and see if she had any grudge against Mrs. Silverdale. It's a pity the second maid's so ill. We can't get anything out of her for a while, I'm afraid. And I want her for another thing: to see if Mrs. Silverdale doped herself at all. But I expect, if she did, that I'll be able to pick up some hint of it somewhere or other. And of course, if the poison turns out to be a non-dope kind, that line of inquiry drops into a subsidiary place.”
