The Margaret Code

MEET THE DETECTIVE DUO YOU'LL NEVER FORGET

For readers of The Marlow Murder Club, Richard Osman and The List of Suspicious Things

89-year-old Margaret has lived on Garnon Crescent all her life, except for those few years she never talks about. She knows all the neighbours; their hopes, their heartbreaks.

Only recently, Margaret's memory isn't what it used to be. She is sure Barbara, her best friend and neighbour, told her something important. Something she was supposed to remember.

When Barbara is found dead, Margaret determines to recover her missing memory. She and her grandson James begin to investigate, but soon strange incidents occur in her home. Margaret's daughter thinks her memory is getting worse, but Margaret knows somebody wants her out of the way.

Because Margaret holds the key to solving this crime. If only she could remember where she put it.
