ROBERT ELDRIDGE sat back in his seat. The train would be moving presently. He looked at his watch…. Twelve minutes past seven. He had perhaps entered the train too soon. His compartment might at the last moment be invaded. Then, of course, he would have to move into another.
He hoped it had not been noticed— this anxiety of his to avoid his fellow-men whenever he caught the 7:15 from Fenchurch Street. But that was hardly likely.
