"Not one of PD James' best"
The story plods along at the pace of the Thames river and the narrator seems a little bored by it. All the different points of view are distracting.
"Laborious"
There were several interesting characteristics about the plot, but the story plodded along. Some of the sub-plots really added little to the story or the suspense. this was my first read of a P.D. James novel. Not sure I would rush to read another. Funny that the setting was a publishing house. I think P.D. would have benefitted from an editor that insisted on carving out a quarter of the manuscript.
