Featuring six stories, this collection brings together Daisy Wells, Hazel Wong and their friends Alexander and George, as well as Hazel's sisters, Rose and May Wong. From the artfully sinister 'The Case of the Second Scream', set aboard the ship carrying Daisy and Hazel's back from Hong Kong, to 'The Case of the Uninvited Guest', where a Uncle Felix and Aunt Lucy's wedding ceremony is the target for an unlikely threat. 'The Hound of Weston School' sees the Junior Pinkerton's lead the detecting, and May Wong steps up and shows her ambition to be the greatest spy ever when war breaks out in 'May Wong and the Deadly Flat'.
