The Black Dudley Murder Author:Margery Allingham Murder turns a weekend house party at Black Dudley Manor into a deadly affair when the host is discovered brutally slain. Nor do gruesome rituals, callous interrogations, and perilous traps add to the fun. Fatal mystification might win the day, if Albert Campion were not there to sift through the motives and clues as with brilliant detection and... more » his signature charm he penetrates the heart of the crime.« less
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."
