As always in the Sir John Appleby's books, the story is complex, full of twists and strange coincidences, eccentric behavior, obscure quotations... and the expectation that the reader has a general sense of (Western) culture. In this particular book, Sir John Appleby is accosted - in his club, no less, where the motto is "Silence is observed", and not less than twice in a single day!- by casual acquaintances, each of whom has a strange story to tell. The first is a collector of fake manuscripts (eccentric number 1), who is dismayed to find that the fake he has acquired, is faked! That it is: it was produced AFTER the faker whose work he's interested in, had died. He intends to take this up with his book dealer. A few hours later, a relative of Sir John Appleby's wife, Sir Gabriel Gulliver, who works in an art museum, comes to him with another strange tale: a gorgeous young woman has brought in a genuine Rembrandt for appraisal, but the second she noticed Sir Gabriel's assistant, Jimmy Heffer, she packs up her parcel and disappears. Strange, what?
Within hours the two stories converge: the book dealer from the faked fake manuscript is murdered, and found standing over him with a gun in his hand, is Jimmy Heffer. It takes some time before he can be exonerated, due to the eccentric behavior of the local charwoman (eccentric nr 2), but that is not the end of the saga. Sir John Appleby, now very high up at Scotland Yard and a paper shuffler, is secretly pleased to be on the case once more, even if it means that his wife's dinner parties are disrupted, he has to climb up and down the rooftops of London, and meets a malignant old miser (eccentric nr 3) in a decaying country mansion.
Good fun!
