Its 1936 and, since we left him six months ago at the conclusion of the dark actions at Mersham Castle in Sweet Poison, Lord Edward Corinth has spent his time in New York falling out of love. Meanwhile Verity Browne has spent a slightly more interesting time in Madrid discovering the joys of sex, reporting on the lead-up to the Spanish Civil War and getting more involved in the Communist Party. When Verity's revered ex-lover and political mentor is found guilty of murder by the Spanish authorities, Lord Edward leaps upon his white charger (in this case a de Havilland Dragon Rapide from Croydon Aerodrome) to extricate the fellow from jail by discovering who really did the dirty deed. Before you can say "viva Franco" the body count is raising both in Spain and back in Blighty.
The novel like its predecessor is highly historically accurate and there-in lies one of the problems as all the characters are portrayed as extremes of their time and consequently none come across as a likable or even believable.
Lord Edward is an almost carbon copy of Lord Peter Wimsey right down to his unrequited love for a professional female who his family find perplexing. But unlike Wimsey, Corinth is a disappointing detective. He stumbles on various truths because they literally come up to him and slap him in the face. He is helped because the police are so incompetent as to beggar belief (I'm not going to give the game away but the major clue in a police photograph that the boys in blue ignore is just plain stupid).
This isn't Dorothy L Sayers, the heroine's totally redundant and, for a whodunit explicit, sex scene proves that and I don't remember Lord Peter leaping into bed with another 'gal' seconds after saying goodbye to Harriet Vane the way Lord Edward does having taken his leave from Verity. More importantly the story telling is not in the same league. Miss Sayers knew how to tweak interest by giving all the information the reader needed throughout the story in little snippets liberally surrounded by red herrings. Like in Sweet Poison, David Roberts relies on an individual revealing an hitherto totally unrecorded history and event, which brings the story together for an unsatisfactory conclusion.
I won't be buying the next volume in the series in hardback. I might purchase the cheaper paperback to follow the adventures of Corinth and Browne but for the history rather than the detection.
