In the meantime, nothing more was seen of Boris. He did not come to the flat, and Julius and the car waited in vain. Tuppence gave herself over to new meditations. Whilst admitting the truth of Julius’s objections, she had nevertheless not entirely relinquished the idea of appealing to Sir James Peel Edgerton. Indeed, she had gone so far as to look up his address in the Red Book . Had he meant to warn her that day? If so, why? Surely she was at least entitled to demand an explanation. He had looked at her so kindly. Perhaps he might tell them something concerning Mrs. Vandemeyer which might lead to a clue to Tommy’s whereabouts.

Anyway, Tuppence decided, with her usual shake of the shoulders, it was worth trying, and try it she would. Sunday was her afternoon out. She would meet Julius, persuade him to her point of view, and they would beard the lion in his den.
