I purchased a copy of this book some years ago when I first moved onto a narrowboat to live and the subtle terror of the stories gripped me then and I have never quite shaken off the feeling.
Rolt knew his stuff and, from his background of all things mechanical and nautical, he has produced a finely crafted set of stories which alarm and disturb as all "spooky" stories should. Tom Rolt was heavily involved in canals and canal folk- in fact, if it had not been for him and his good lady Sylvia and a few dedicated friends, the canals would more than likely have been lost to us forever.
He writes about what he knows in a very fine and precise fashion and tells a rattling good tale into the bargain. If you like M R James or E Nesbit, this volume is for you.
