An extraordinary, gloriously uplifting novel about the power of friendship and the puzzling ties that bind us Clayton Stumper might be twenty-six years old, but he dresses like your grandpa and drinks sherry like your aunt. Abandoned at birth on the steps of the Fellowship of Puzzlemakers, he was raised by a group of eccentric enigmatologists and now finds himself among the last survivors of a fading institution. When the esteemed crossword compiler and main maternal presence in Clayton's life, Pippa Allsbrook, passes away, she bestows her final puzzle on him: a promise to reveal the mystery of his parentage and prepare him for life beyond the walls of the commune. As Clay begins to unpick the clues, he uncovers something even the Fellowship have never been able to solve—and it's a secret that has the potential to change everything.
