David I. Masson began publishing sf with "Traveller's Rest" for NEW WORLDS in 1965; his fiction, including this extraordinarily intense study in the distortion of PERCEPTION, was assembled in The Caltraps of Time (1968), which single volume established his strong reputation as a writer of vigorously experimental, vivid, often scientifically sound stories. Notable among them, and reflecting his close and informed interest in LINGUISTICS, were "Not so Certain" (1967) and the brilliant time travel story "A Two-Timer" (1966), told entirely in language appropriate to 1683, the year from which the inadvertent time traveller is whisked into the future.

Each of DIM's stories seems to be a solution to some cognitive or creative problem or challenge...
