Praise for David Roberts 'A classic murder mystery with as complex a plot as one could hope for and a most engaging pair of amateur sleuths.' ( Sweet Poison ) Charles Osborne, author of The Life and Crimes of Agatha Christie 'This is a witty and meticulous recreation of the class- ridden middle England of the 1930s... a perfect example of golden-age mystery traditions with the cobwebs swept away.' ( Bones of the Buried ) Guardian 'The plot is both intricate and enthralling, like Poirot on the high seas, and lovingly recorded by an author with a meticulous eye and a huge sense of fun.' Michael Dobbs.
