“But not quite so wholeheartedly,” Shayne pointed out. “She could have announced her engagement to him without forfeiting a fortune. No, we can’t count Marlow out. Sex jealousy and greed motivate ninety-nine per cent of our murders. He had plenty of reason to be jealous.”

“He didn’t look like a killer to me — the glimpse I had of him in the hotel tonight.”

“He was a little off par,” Shayne explained. “No man puts his best foot forward when he’s wearing off a Mickey Finn. Bugler fed him a doped drink when he called on him this evening and began laying Bugler out for the way he’s been running around with her.”

Rourke’s head came up and his eyes wavered toward Shayne. “You get around, don’t you? Suppose Arch knew Helen was married to Marlow?”

Shayne tugged at his ear lobe. “I wasn’t in on much of the conference. From what I saw and heard, Marlow was getting nasty and Bugler eased him off with private stock before he could make a scene at the inn.”

Rourke tested his strength once more with his palms flat on the couch, came shakily to a sitting position. He reached for the Scotch bottle and Shayne warned, “You’re hitting the bottle pretty heavy, Tim.”

Rourke nodded cheerfully. “Why not? You’re not one to deliver a temperance lecture.” He took a sight on the cognac bottle and saw that it was more than half full. “You’re not up to par tonight, Mike.”

“I have things to do.”

“Tonight?” Rourke attempted to register astonishment.

“Certain things,” Shayne explained, “are best accomplished under the cloak of darkness.”
