This was an excellent book fast-paced and full of action, more than I was expecting, knowing the key player from previous Dan Shepherd books I knew the character and he was excellent in this story, he was level headed, and organised and the book was exciting from start to finish, would like to know if there was going to be another to finish off the story as it was left with an opening if there was going to be a continuation. Lots of information about what they were doing and the procedures that they undertook to be invisible in situations and the respect that the main operator gained by his knowledge and understanding of the situation, fascinating details about a superyacht that was being used and the experiences that were used and money being of no object gave the yacht the services it needed for this story to be so good. Would recommend to everyone to read, and it was nice that there was no un-necessary swearing or any sex with too much detail, it was about a special op carried out to a high standard. It is well worth reading.
