 You know, it's just the same as you, Inspector. What do you mean? Well, you recognized the fact that Danny Murray was the killer. The minute he accused Miss Brewer of using a hypodermic to administer the poison, didn't you? That's the sugar, Bart. Here you are. Thank you. You're welcome. You knew he was a murderer then because he couldn't have known that the hypodermic had been used unless he'd been there when it was used.
