A sinister case of deadly poisoned chocolates from Sodbury Crosss high street shop haunts the group of friends and relatives assembled at Bellegarde, among the orchards of peach-fancier Marcus Chesney. To prove a point about how the sweets could have been poisoned under the nose of the shopkeeper, Chesney stages an elaborate memory game to test whether any of his guests can see beyond their black spectacles; that is, to see the truth without assumptions as witnesses.
During the test which is also being filmed Chesney is murdered by his accomplice, dressed head to toe in an invisible man disguise. The keen wits of Dr Gideon Fell are called for to crack this brazen and bizarre murder committed in full view of an audience.
Also known by its US title The Problem of the Green Capsule, this classic novel is widely regarded as one of John Dickson Carrs masterpieces and remains among the greatest impossible crime mysteries of all time.
