Talbot stared at him. For the first time Pitt saw in his face that he was frightened. He had cause to be. If he were wrong, either for Ryerson or against him, not a matter of fact but of judgment, he would be ruined. He would take the blame, possibly for others’ mistakes, men of greater power and with more to lose.

“So Mr. Ryerson is at home?” Pitt asked.

“As far as I know,” Talbot said. “He certainly isn’t here. We asked him if he could help us, and he said he couldn’t. He said he thought Miss Zakhari was innocent. He didn’t believe she would have killed anyone, unless they were threatening her life, in which case it wouldn’t be a crime.” He shrugged. “I could have written it all down without bothering to ask him. He said the only thing he could-he doesn’t know anything about it, he only just arrived-to protect her honor, and all that. Decent men don’t say a woman’s a whore, even if she is and we all know it. He said she wouldn’t have killed anyone without a reason, but then he wouldn’t say she had, would he? Apart from anything else, it would make him look like he was betraying her-and that his mistress, which we all know that she is, was a likely murderess and he knew it. And as I said, she didn’t deny the gun was hers. We asked the manservant she has, and he admitted it as well. He kept it clean and oiled, and so on.”

“Why did she have a gun?”

Talbot spread his hands. “God knows! She did, that’s all that matters. Look, sir-Constable Black found her in the garden with the murdered body of an old lover of hers stuck in a wheelbarrow. What more do you want of us?”

“Nothing,” Pitt conceded. “Thank you for your patience, Inspector Talbot. If there’s anything further I’ll come back.” He hesitated a moment, then smiled. “Good luck.”

Talbot rolled his eyes, but his expression softened for a moment. “Thank you,” he said with a touch of sarcasm. “I wish I could walk away from it so easily.”
