“A missionary,” said Miss Temple slowly.
Ellery smiled. “Right again, Miss Temple. I felt convinced that our benevolent-appearing, soft-speaking little corpse with the breviary and religious tracts in his bag had been a Catholic missionary from China!”

Some one rapped thunderously on the door against which Inspector Queen’s slender shoulder-blades were resting, and the old man turned quickly and opened the door. The visitor was Sergeant Velie, hard-bitten and grim as usual.
Ellery murmured: “I beg your pardon,” and hurried to the door. They watched the three men conferring with open expressions of anxiety and apprehension. The Sergeant was rumbling something ominous-sounding, the Inspector was looking triumphant, and Ellery was nodding vigorously at every murmur. Then something passed from Velie’s beefy hand to Ellery’s, and Ellery turned his back and examined it, and turned and smiled and put what he was holding into his pocket. The Sergeant leaned back against the door, towering beside Inspector Queen.
“Now I reasoned that, if this was true, the missionary had come either to sell stamps or jewels, or to buy them¯the two all-inclusive classifications. The cheapness of the man’s attire, his vocation, the long journey he had made, convinced me that he was not a buyer. Then he was a seller. This fitted well, too, with his general air of secrecy. He had something in a stamp or jewel to sell Donald Kirk, something valuable, to judge from his reticent attitude. It was therefore evident that he must have been murdered for possession of the stamp or jewel he had come all the way from China to sell. It was even possible to infer that, since Kirk is a specialist on stamps of China, the missionary was probably the owner of a Chinese stamp rather than a jewel. This wasn’t certain, but it seemed the better possibility.
Some one gasped. But when Ellery searched their faces he met only stubbornly furtive stares.
He smiled and took from his pocket a long manilla envelope. From this envelope he took another, smaller envelope of queer foreign appearance, with an address (presumably) in Chinese and a cancelled stamp in one corner. “Messrs. Kirk and Macgowan.” The two men rose uncertainly. “We may as well call upon our two philatelists. What do you make of this?”
They came forward, reluctant but curious. Kirk took the envelope slowly, Macgowan peering over his shoulder. And then, simultaneously, they cried out and began to talk to each other excitedly in undertones.
