Colin Caffell - perhaps understandably given what he's been through - evinces a strong belief in his book in intuition, precognition and foreshadowing. He makes the silhouette remark describing Jeremy's arrival at his house on the night of the housewarming. Poignantly, Colin later expresses regret that it was Julie Mugford who read the twins their bedtime story that night, the last ever time Colin had an opportunity to do it himself.
"When Jeremy told me that he saw the boys as a 'millstone' round my neck, I pointed out that this was far from the truth: the twins were not only my sons but my closest friends, and being a full time parent was my own choice - something I thoroughly enjoyed" (Page 27)
I was surprised how little detective work the book contains. Colin was excluded from the process that led to Jeremy's trial because for a part of it he was considered as a possible accomplice or co-conspirator himself. He certainly accepts Jeremy's guilt and Chapter 25 contains some unpleasant correspondence between them, but the book mainly deals with his recovery and memories of his children.
