But first he had to warn Frances, and before he could do that he had to get her away from the other two. If he told her when they were there, Buster would probably call a cop and stop him fixing Moe.

The black-and-white checkered police car swung into Lennox Avenue, slowed to a crawl while Conrad leaned out of the window to catch a glimpse of the numbers of the houses.

“Across the road, about ten yards up,” he said to Bardin, who was driving.

The shadow hurriedly ducked back out of sight as Conrad turned his head to look at the window.
