Jack and Sal, two people drifting in and out of love. Jack searches for clues, for a pattern, for an explanation to life's events. Perhaps the answer is in evolution, in dopamine, in chaos theory, or maybe it can be found in the minutiae of domesticity where the majority of life's dramas unfold. Here, Anthony Cropper has produced a delicately detailed account of a troubled relationship, with a series of micro-stories and incidents that recount the intimate lies, loves and lives of Jack and Sal and their close friend Paula.
