I just like these books, the plotting and the characters, how they make their way through life, competently. I also enjoy the writing and the plotting, which provides lots of action across the Continent and at home.
We see a flashback of Liz Carlyle's time in Liverpool Special Branch during her training and this provides extra suspense during the investigation. And, there is also an appearance by her current beau - I liked the mix of personal and professional.
I found the ending more problematical. There was an abrupt change of perspective from Peggy, anxious and doing all the right things, to Liz , abrupt enough that we lose sight of Peggy for a while. It creates a tension as we also lose sight of a key piece of intelligence but it feels a little crudely executed. The ending is also rather abrupt and I couldn't decide whether it worked. It was very visual - I saw one of those rapid, silent sequences of images catching us up on what was happening, without spending a lot of time on something that is really very familiar. That was quite efficient and it made sense that the personal part was told in retrospect and not shown in detail - this is a spy thriller, after all. However, it felt like Dame Stella had just lost interest now the main story was over. On to the next book, eh?
