Having been a long time fan of Elizabeth George, I was disappointed with this book. It returns to the diary format of 'Playing for the Ashes' but lacks it's gripping story line. The plot of A Traitor to Memory is tangled and to me, far-fetched and it took a while for the diary entries to fit into the story, which made it hard going. Usually, I find it's hard to put down a new Elizabeth George, but with this story, I struggled to continue. Quite apart from the almost boring 'diary entries'and the seeming lack of a convincing plot, a major dissappointment is the side-lining of the usual characters. In the last book, it seemed that Barbara Havers was developing a relationship with her neighbour, but there was no mention of him or his daughter this time. Deborah and St James barely featured at all and even the relationship between Lynley and Helen is only briefly incorporated into the story.
Part of the enjoyment of this series has been following the lives of the main characters, to have them all-but-removed is disappointing, but would not have mattered so much had the main story been a good one. Unfortunately, it was not.
