London 1946. A decade may have passed since she solved the ffolkes Manor murder case narrated in The Act of Roger Murgatroyd, but Evadne Mount, herself the irrepressible author of countless bestselling whodunits, has aged as little as most fictional sleuths tend to do. And here she is again, seconded as ever by her loyal, long-suffering partner-in-detection, Chief-Inspector Trubshawe formerly of Scotland Yard, on the trail of an even more fiendishly ingenious killer.

An actress is poisoned, not just on camera but in full view of a crowded film set. Only five people had an opportunity to administer the poison - yet not one of them had a conceivable motive. As Evadne Mount discovers, each of them is implicated in a web of deceit whose lethal ramifications extend far beyond the confines of the studio in which the murder was committed.

A Mysterious Affair of Style is a hugely entertaining homage to the Golden Age of English murder mysteries and its most celebrated practitioner. Welcome to the world of Evadne Mount.
