An intriguing discovery for crime fiction fans . . .
One Tuesday evening a group gathers at Miss Marple's house and the conversation turns to unsolved crimes . . .
. . . The case of the disappearing bloodstains; the thief who committed his crime twice over; the message on the death-bed of a poisoned man which read "heap of fish"; the strange case of the invisible will; a spiritualist who warned that "Blue Geranium" meant death . . .
Now you pit your wits against the powers of deduction of the "Tuesday Night Club".
