Colin Caffell is a sculptor and ceramicist who, in 1985, lost his ex-wife Sheila and their twin sons to the Whitehouse Farm Murders. He wrote In Search of the Rainbow's End in the wake of the press scrutiny that followed. Caffell later became a counsellor and workshop facilitator, specialising in the field of trauma and loss. He now lives in the far west of Cornwall with his wife and their daughter, where they run their own art gallery. He is also an elected member of the Penwith Society of Arts in Cornwall.
