The police official and the detective had dined together in the small bar parlour on Colwyn's return from driving Mr. Cromering and Sir Henry Durwood to Heathfield Station. The superintendent had done more than justice to the meal, and a subsequent glass of the smugglers' brandy had so mellowed the milk of human kindness in his composition that he felt inclined for a little friendly conversation with his companion. "You are very confident," said Colwyn. "Of course I am confident. I have reason to be so. Everything I have seen to-day supports my original theory about this crime." "And what is your theory as to the manner in which this crime was committed? I have gathered a general idea of the line you are taking by listening to your conversation this afternoon, but I should like you to state your theory in precise terms. It is an interesting case, with some peculiar points about it which a frank discussion might help to elucidate." Superintendent Galloway looked suspiciously at Colwyn out of his small hard grey eyes. His official mind scented an attempt to trap him, and his Norfolk prudence prompted him to get what he could from the detective but to give nothing away in return. "I see you're suspicious of me, Galloway," continued Colwyn with a smile. "You've heard of city detectives and their ways, and you're thinking to yourself that a Norfolk man is more than a match for any of them." This sally was so akin to what was passing in the superintendent's mind that a grim smile momentarily relaxed his rugged features. "My thoughts are my own, I suppose," he said. "Not when you've just given them away," replied Colwyn, in a bantering tone. "My dear Galloway, your ingenuous countenance is a mirror to your mind, in which he who runs may read. But you are quite wrong in suspecting me. I have no ulterior motive. My only interest in this crime--or in any crime--is to solve it. Anybody can have the credit, as far as I am concerned. Newspaper notoriety is nothing to me." "You've managed to get a good deal of it without looking for it, then," retorted the superintendent cannily. "It was only the other day I was reading a long article in one of the London newspapers about you, praising you for tracking the criminals in the Treasury Bonds case. The police were not mentioned."
