I was a little put off by the blurb, which in the event turned out to be slightly inaccurate. However, the first couple of chapters do set the scene for an interesting story, even if the premise is one that is quite familiar. Granny with an interesting past sets off to revisit it and contrives to have her 18 year old grandson to go with her. He is approached by a person who may or may not be from one of ‘those’ services. Granny of course needs to bring him up to speed...What larks!
