By the end you always feel that DCI Adam Dalgliesh always had a suspect in mind as to the murder of maid Sally Jupp.
The prime suspect is medic Krishna Mehta. He seems to have been in love with her. Even proposing to Sally and then getting rebuffed.
Dalgliesh knows there are other players. Most of them are in the Mehta family itself. A lot of them not being entirely truthful to the police.
Like the first story in the third series. I felt underwhelmed by the denouement. It is like eating a meal and then coming away with still feeling undernourished.
Carvel does well in adding bits of characterisation to Dalgliesh. So he does not come across as a generic crimebuster.
