investigations as keenly and methodically as any practised detective, for he rather prided himself upon the manner in which he made discoveries about persons, and frequently astounded his patients by his knowledge of their actions and movements, which they believed only known to themselves. At last, however, he exhausted all the points possible to investigate without a post-mortem, and just as the church clock struck three we came forth, Warr locking the door of the outhouse, while Knight left us to ride on his bicycle into Northampton to report to the headquarters of the constabulary. Pink’s way lay past my house, for he lived in a big, square, comfortable house about a quarter of a mile out of the village, on the London road, and as we walked together up the silent street, he suddenly said— “Do you know, Woodhouse, I have a firm belief that the young fellow has been murdered by some woman!
