Goodall scratched his chin, reflectively. “That’s all very well, as far as it goes. Robbery—you say, for possession of the Stuart antiques. Worth what? I’m not an expert—but for the sake of argument we’ll put it at a matter of hundreds. And we sha’n’t be so very far out, at that! Now, Mr. Bathurst, what was there so peculiarly attractive about these antiques—or about one of them—to spell Mason’s murder?” He leaned forward still further in his seat and his voice cut across the compartment quietly insistent and definitely certain. “To kill Laurence Stewart? To send you—and you—and me, to Assynton, on a summer evening—_wondering_! Eh, Mr. Bathurst—tell me that!” His eyes blazed with a mingled excitement and determination, as he watched his _vis-à-vis_. Bathurst rubbed his hands, appreciatively! “Excellent, Inspector, excellent. That’s a question that I should very much like to be able to answer.” “Which of the antiques, Mr. Bathurst? Which one? And not a clue that you can call a clue as to where they’ve gone—except a sneezing woman,” he remarked semi-humorously. “Tell me,” said Anthony, “I’m interested.” He listened carefully while Goodall—despite his opposite intention when the journey started—related the trenchant evidence of Edward Druce—night-watchman. “So they were at the Hanover Galleries at midnight, were they? That’s important! That gives us a definite time-anchor.” He spoke to Goodall with decision. “I think with you, Inspector Goodall, that the two cases are connected without a doubt. But it’s a mistake to theorize without data—let’s wait till we pick up the threads a bit this end. As you say—which one of the three antiques were they after? It’s as bad as ‘finding the lady’—with Mary, Queen of Scots, as the lady.” He grinned at Daventry, who had been following the interchange of ideas with the keenest possible attention. Suddenly Peter slapped his thigh with excitement. “By Jove!” he cried, “Mary, Queen of Scots—that reminds me—what an idiot I’ve been not to tell you before.” Then he paused with a hint of apology. “So much has happened since, that it has been driven completely out of my mind.” “You become more interesting hourly, Daventry,” remarked Anthony. “Out with it, whatever it is—before you forget it again.” Peter waved the sarcasm aside.
