Another ~ frankly ~ idiotic story about a medium and a random message from beyond the grave. In this one the visitor turns out to be none other than some Very Ancient Greek named Machaon, son of Aesculapius (y'know, the one who invented medicine), who struggles through the ether or ectoplasm or whatever to deliver to our Unnamed Narrator, who just happens to live in a little town named Tilling, in a house with a garden room, the verdict that U.N.'s faithful manservant, currently lying in hospital stricken with cancer, should be treated with X-rays. [No, I'm not making this up: EFB is.] The whole thing is so preposterous that I'm not prepared to spend any more time on it.
But maybe you'll have better luck with it: it's available online here.
