In this volume, originally published in 1978, the authors survey the historical and contemporary research literature pertaining to two-dimensional visual-geometric illusions. They bring together much of the known data, summarising and evaluating theories that have been offered to explain these phenomena. Coren and Girgus provide a new conceptual framework that suggest that visual illusions are not unitary phenomena. Within this framework, illusions do not represent a breakdown in normal perceptual processing. Rather, it is proposed that each illusion is produced by a number of mechanisms operating at different levels in the visual information processing system. The book contains an extensive collection of illusion figures. It will be essential reading for all of those concerned with vision and visual perception, since it integrates the study of illusions into the main body of psychological and perceptual theories at the time.

In this mix of mystery and high comedy, set amid the glories of the Rocky Mountain foothills, television photographer Phoebe Fairfax and her gorgeous but decidedly dotty on-air colleague Candi Sinclair are taping at a psychic fair. Shortly after they shoot an interview with him, arch-creep Jonathan Webster collapses and dies, murdered with a dose of agricultural pesticide administered in a most unusual way. The police immediately suspect his common law wife Tracy McMurtry, an old high-school pal of Candi's. The fact that Webster used Tracy as his personal punching bag when he wasn't busy losing all her money on one of his compulsive gambling sprees puts her at the top of their list.

Phoebe finds the answer to the mystery of Webster's murder in the midst of a spring blizzard high in the foothills west of Calgary. Or does she? Could it be that all her efforts only serve to prove that seeing truly can be deceiving? A Globe and Mail best seller.
