Boris’s words had aroused a new train of thought in Tommy’s mind. Clearly Whittington was making the journey alone, while the other remained in London. Therefore he was left with a choice as to which he would follow. Obviously, he could not follow both of them unless⁠—Like Boris, he glanced up at the clock, and then to the announcement board of the trains. The Bournemouth train left at 3:30. It was now ten past. Whittington and Boris were walking up and down by the bookstall. He gave one doubtful look at them, then hurried into an adjacent telephone box. He dared not waste time in trying to get hold of Tuppence. In all probability she was still in the neighbourhood of South Audley Mansions. But there remained another ally. He rang up the Ritz and asked for Julius Hersheimmer. There was a click and a buzz. Oh, if only the young American was in his room! There was another click, and then “Hello” in unmistakable accents came over the wire.

“That you, Hersheimmer? Beresford speaking. I’m at Waterloo. I’ve followed Whittington and another man here. No time to explain. Whittington’s off to Bournemouth by the 3:30. Can you get there by then?”
