Spade seemed mildly amused. “Don’t be a hog,” he said. “You oughtn’t try to pin more than one murder at a time on me. Your first idea that I knocked Thursby off because he’d killed Miles falls apart if you blame me for killing Miles too.”

“You haven’t heard me say you killed anybody,” Dundy replied. “You’re the one that keeps bringing that up. But suppose I did. You could have blipped them both. There’s a way of figuring it.”

“Uh-huh. I could’ve butchered Miles to get his wife, and then Thursby so I could hang Miles’s killing on him. That’s a hell of a swell system, or will be when I can give somebody else the bump and hang Thursby’s on them. How long am I supposed to keep that up? Are you going to put your hand on my shoulder for all the killings in San Francisco from now on?”

Tom said: “Aw, cut the comedy, Sam. You know damned well we don’t like this any more than you do, but we got our work to do.”

“I hope you’ve got something to do besides pop in here early every morning with a lot of damned fool questions.”

“And get damned lying answers,” Dundy added deliberately.

“Take it easy,” Spade cautioned him.

Dundy looked him up and down and then looked him straight in the eyes. “If you say there was nothing between you and Archer’s wife,” he said, “you’re a liar, and I’m telling you so.”

A startled look came into Tom’s small eyes.

Spade moistened his lips with the tip of his tongue and asked: “Is that the hot tip that brought you here at this ungodly time of night?”

“That’s one of them.”
