His car is in the driveway?… Good, then he’s home.”
“Now, how do you want us to work it, Chief?” asked the Boston detective.
“Just drive along, and when you come to the house, stop,” said Lanigan. “Keep your motor running, just as you would if you stopped to ask someone for directions. Madelaine will get out. The house will be on her side. Keep your coat buttoned and push the collar up, Madelaine. That’s fine. Put your head down a little. That’s right. Then you just go up and ring the bell. When the door opens and he answers, you let him get a good look at you and ask how to get onto the road to Boston. Nothing to be afraid of. The worst he can do is slam the door in your face.” He turned to the policeman. “You just sit tight unless you see something unusual.”
“Like what?”
“Like anything different from the way a man normally would behave if somebody asked him directions. We’ll be behind you, but we’ll keep out of sight. If we see you get out of the car, we’ll come a-running. All right?”
“Check.”
The two cars began to move, Madelaine Spinney and the policeman from Boston in one, Lanigan and Jennings in the other. When they reached Tarlow’s point, the woman got out and walked up to Begg’s house. She rang the bell, and a moment later the door was thrown open. “Yes?”
As instructed, she raised her head from her coat collar. The two stared at each other.
“You!”
The policeman moved rapidly toward the house.
