Another political case: minister (ag & fish, or something similarly minor) disappears; see title, with question mark. This is very much an English detective story; it belongs to the boring Knox school, rather than to the boring Freeman/Crofts school. Amateur sleuth (artist) theorises, mulls, cogitates, and restates the evidence in every chapter. Joy! The plot involves (deep breath) a veiled lady, blackmail, bigamy, and a wicked cousin from America (introduced out of nowhere). At least there are no boats or trains.
