Heatherlegh is the dearest doctor that ever was, and his invariable prescription to all his patients is, "lie low, go slow, and keep cool." He says that more men are killed by overwork than the importance of this world justifies. He maintains that overwork slew Pansay, who died under his hands about three years ago. He has, of course, the right to speak authoritatively, and he laughs at my theory that there was a crack in Pansay's head and a little bit of the Dark World came through and pressed him to death. "Pansay went off the handle," says Heatherlegh, "after the stimulus of long leave at Home. He may or he may not have behaved like a blackguard to Mrs. Keith-Wessington. My notion is that the work of the Katabundi Settlement ran him off his legs, and that he took to brooding and making much of an ordinary P. & O. flirtation. He certainly was engaged to Miss Mannering, and she certainly broke off the engagement. Then he took a feverish chill and all that nonsense about ghosts developed. Overwork started his illness, kept it alight, and killed him poor devil. Write him off to the System-one man to take the work of two and a half men."
