Genuinely delicious and fascinating mystery novel that utterly perturbs and bewilders the reader. A story about an amateur dramatic society might be enough for some, a story about an appeal for aid for a sick child might be enough for some, a story about people returning from time spent working as medical volunteers in violent parts of the world might be enough for some, but here we have all three, and one or two more, woven together fiendishly through an epistolary narrative of emails and text messages into a complex tale that keeps the reader guessing until the final solution is presented.
