Masters waved his hand. "And is that, Mr. Rainger," he said, "all you've got to accuse a man of murder?"
"No. I am going to tell you what John Bohun did.”
"He arrived here at one-thirty, and left his car in the driveway.. He was wearing evening-clothes and light patentleather evening shoes-"
"How do you know that?"
"I use my brain, you see," nodded Rainger, bending forward. "I got that from the maid who went into his room this morning to light the fire. She saw the clothes scattered. She also told me (eh?) that his bed was still made and had not been slept in last night."
After a pause Masters said, "Take that down, Potter."
"He walked straight down to the pavilion, as he and Marcia had arranged. (The fool lied to you when he said he didn't know Marcia was there, and yet he admitted she had told him she was going there. He knew Marcia never changed her mind; you'll see why he lied.) Well, the dog barked for longer than usual. Why? Because of the time it took him to walk down. If he'd only gone into the house, the dog would have shut up."
Inspector Potter uttered an exclamation.
"You're suggesting-?" said Masters quickly.
"Oh, he was her lover," said Rainger. "I know that." He leaned over suddenly and spat into the fire.
