 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 men that he accused Miss Brewer of using a hypodermic to administer the poison, didn't you? That's your sugar, Bart. Here you are. Thanks. You're welcome. You knew he was a murderer then because he couldn't have known that a hypodermic had been used unless he'd been there when it was used. Yep.
