Father Brown threw away a daisy-chain he was making, and rose with a wistful look. “Has Major Putnam,” he asked, “got any Eastern curios, idols, weapons and so on, from which one might get a hint?”

“Plenty of those, though not much use, I fear,” replied Cray; “but by all means come into his study.”

As they entered they passed Miss Watson buttoning her gloves for church, and heard the voice of Putnam downstairs still giving a lecture on cookery to the cook. In the Major’s study and den of curios they came suddenly on a third party, silk-hatted and dressed for the street, who was poring over an open book on the smoking-table—a book which he dropped rather guiltily, and turned.

Cray introduced him civilly enough, as Dr Oman, but he showed such disfavour in his very face that Brown guessed the two men, whether Audrey knew it or not, were rivals. Nor was the priest wholly unsympathetic with the prejudice. Dr Oman was a very well-dressed gentleman indeed; well-featured, though almost dark enough for an Asiatic. But Father Brown had to tell himself sharply that one should be in charity even with those who wax their pointed beards, who have small gloved hands, and who speak with perfectly modulated voices.

Cray seemed to find something specially irritating in the small prayer-book in Oman’s dark-gloved hand. “I didn’t know that was in your line,” he said rather rudely.

Oman laughed mildly, but without offence. “This is more so, I know,” he said, laying his hand on the big book he had dropped, “a dictionary of drugs and such things. But it’s rather too large to take to church.” Then he closed the larger book, and there seemed again the faintest touch of hurry and embarrassment.

“I suppose,” said the priest, who seemed anxious to change the subject, “all these spears and things are from India?”

“From everywhere,” answered the doctor. “Putnam is an old soldier, and has been in Mexico and Australia, and the Cannibal Islands for all I know.”

“I hope it was not in the Cannibal Islands,” said Brown, “that he learnt the art of cookery.” And he ran his eyes over the stew-pots or other strange utensils on the wall.

At this moment the jolly subject of their conversation thrust his laughing, lobsterish face into the room. “Come along, Cray,” he cried. “Your lunch is just coming in. And the bells are ringing for those who want to go to church.”
