Mike Ashley's brilliant new collection of whodunnits presents stories that reflect all the excitement, escapism and eccentricity of the 1920s. The Roaring Twenties, the Jazz Age, the Age of Wonderful Nonsense - this was the decade when everyone went a little bit crazy with the euphoria of getting through the War. For a while the 20s seemed to have everything going for it, but beneath the dazzle and glitter lay a darker side.
