I thought this started well with a number of seemingly separate stories. I realised that these would all coalesce as the tale went on and this is indeed what happened.
I have really enjoyed the Rob Ryan Dr Watson series, set in World War I so this was a completely different type of book from this author, for me at least.
Thought it worked reasonably well with a fairly convoluted plot and, without giving too much away, a high octane denouement. Overall only gave this a three star as not convinced some of the characters were well enough drawn for the reader to really care too much what ultimately happened to them.
Quite enjoyable though and if you like this sort of book you should find this well worth reading.
