Lucky Jim
Sir Kingsley Amis named this fine drink after his character in the novel of the same name
It is a martini with 2:1 fresh cucumber juice to Dry Vermouth
Sir Kingsley's suggested its apparent mildness and pleasant green colour might make it an excellent love philtre to press on shy young ladies, if there any of these left anywhere in the land
He evidently didn't move in the same circles as the Two Chaps (see Old Ball and Chain &cet.)
