Love. Lust. Murder. Secrets. The thrilling mystery continues in this suspenseful sequel to The Secret of Kolney Hatch. At the start of 1927, Petunia Pennyworth holds a great secret, and Paul Watson is recovering from the attempt on his life. When yet another murder happens in London, Petunia's life is set on a downward spiral filled with reporters, whispers, and scandal, while Paul settles into the idea that his worries are finally in the past. Resorting to staying in London and living a simple life, Paul agrees to work for Oscar Baker and tries to progress his relationship with Claire only to learn that a new threat stands in his way. When Paul uncovers a letter to his mother from his late Aunt Greta, he feels compelled to return to Whitemoor--to both his Aunt Greta's cottage and the hidden tunnels of Kolney Hatch. With the help of two persistent London detectives, Wicksy and Barnes, both Petunia and Paul unravel truths so incredible that both of their lives will never be the same.
