Granted, this was Allingham's first Campion mystery, and supposedly they got better, but I found this to be boring and unreadable and gave up about 70 pages from the end. It's not a country-house mystery as one is led to believe, but an interminable trial of following a number of house guests trapped in the place with some criminals after a stolen something. Readers in 1929 didn't know Campion (not the main character here) was her prime detective, so they were led to believe he might be the culprit. Later readers know he isn't.
One other oddity I found was that the author misuses the word "infer" where she really meant "imply."
