“No.” Wolfe was curt. “In all that area the police are so far ahead that we could never catch up. I have explained that. With our meager forces we must try to find a trail not already explored. Has anyone a suggestion for Fred?”
They exchanged glances. No one volunteered.
Wolfe nodded. “It is certainly difficult. One way to avoid panting along at the heels of the police, with the air polluted by their dust, is to make an assumption that they may not have made, and explore it. Let’s try one. I assume that Tuesday afternoon, when the car stopped at the corner and the woman driver told the boy to get a cop, the man in the car with her was Matthew Birch.”
Saul frowned. “I don’t get it, Mr. Wolfe.”
“Good. Then it probably hasn’t occurred to the police. I admit it is extremely tenuous. But later that day, that night, that same car ran over Birch and killed him, in a place and manner indicating that it had carried him to the spot. Therefore, since he was in the car late in the evening, why not assume that he was in it early in the evening? I choose so to assume.”
Saul maintained his frown. “But the way it stands, wouldn’t the assumption be that the man who ran the car over the boy Wednesday was the one who had been with the woman Tuesday? Because he knew the boy could identify him? And on Wednesday Birch was dead.”
“That’s probably the police assumption,” Wolfe conceded. “Its worth is obvious, so I don’t reject it; I merely ignore it and substitute one of my own. Even a false assumption may serve a purpose. Columbus assumed that there was nothing but water between him and the treasures of the Orient, and he bumped into a continent.” His eyes moved. “I don’t expect you to bump into a continent, Fred, but you will proceed on my assumption that Birch was in the car with the woman. Try either to validate it or to disprove it. Take a hundred dollars-no, take three hundred, you never waste money. Archie will supply you with a photograph of Birch.” He turned to me. “They should all have photographs of everyone involved. Can you get them from Mr. Cohen?”
“Not tonight. In the morning.”
“Do so.”
He surveyed his meager forces, left to right and back again. “Gentlemen, I trust I have not dulled your ardor by dwelling on the hopelessness of this enterprise. I wanted you to understand that the situation is such that any tidbit will be a feast. I have on occasion expected much of you; this time I expect nothing. It is likely that-”
The doorbell rang.
