Read this book back in the early 90's around its release, as borrowed from a friend that had read it and this was the first book I could not physically put down. Loved the suspense and the characters, as this was the first book read by this author.
Over time have read the other books in this series, but this one remains special as still resides in my bookcase for unlocking the magic of a good suspense. Have re-read this some years later, and it didn't loose the magic (with recall of the plot).
