“Just as you gambled on quietening me down with one,” Coppell said.

Then Danizon came in with a cup and saucer, looking almost pleadingly at Roger for approbation. Roger took the cup and saucer.

“Thanks. Oh, sergeant—has Mid-Western Division called?”

“Not—not lately, sir.”

“If anyone calls from there, put the call through to me.”

“Right, sir !” Danizon backed out with obvious relief, and Roger began to pour tea. At least he knew that Coppell liked his strong, with plenty of sugar.

“We’ve so much drug pushing going on I think the gamble was worth it. But I can’t see Rachel Warrender defending anyone involved in drugs. I think the alibi was a phoney,” he went on, “but I’m not sure drugs are the trouble. I am sure Rapelli’s terrified.”

“There are orgies,” Coppell pointed out. “The alibi could be genuine.”

“Yes, indeed.” Roger handed him a cup of tea and held out the sugar bowl. “But if the Dunster girl is telling the truth, then two witnesses that I have, who swear they saw Rapelli’s attack on Verdi, are lying. And I don’t think they are.”

“Now I begin to see daylight,” breathed Coppell. “You think the defence was trying to discredit police witnesses in advance?”

“I haven’t the slightest reason to think our witnesses are lying,” Roger replied. “I’ve seen them both after the court hearing. Had to go to a cabinet-making factory in Wandsworth for one and a bakery in Bethnal Green for the other, but their evidence will be all we need. I had to make sure of that, in view of what I’d done in court.”

Coppell gulped down his tea.

“So you’ve some sense. And we’ve two witnesses against Rapelli’s three,” he went on, musingly.

“I can’t imagine any jury believing the sex-party evidence,” said Roger. “The Dunster girl is perfectly capable of that sort of thing, as I said, all the same—” He paused.
