Just another GR refugee. Other than that, I had a stroke in 2004, and read almost anything I can get my hands on, though I have a particular weakness for history, mystery, and historical fiction.
Murder Offstage is a first book in a series ("Posie Parker Mysteries"), and, indeed, is a first novel.
It rather reads as a first novel - the plot is too complicated and frenetic, and only barely avoided having the kitchen sink involved. Murder! Diamond thieves! Kidnapping! Smuggling! Counterfeiting! And to top it all off, a Criminal Mastermind with a cat in his lap.
Alas, not this one.
Did I mention the tired "soused aristocrat with a secret" trope and a plot that just doesn't make terribly much sense?
I got it because the setting, 1921 London, and the supposed focus (the theater scene), but I doubt I'll read another one, frankly.
