This is the fourth of the Thomas Chaloner series, historical mysteries set just after the restoration of the monarchy in Britain following the Civil War and Cromwell's rule. In The Westminster Poisoner, Chaloner investigates a series of murders of government officials, despite interference from his employer, who starts out by telling him who the murderer should be.
As is now standard in this series, Chaloner spends much of the investigation as an outsider to the corrupt world of Restoration London; this provides an interesting perspective, but can become a bit wearing. The Westminster Poisoner is quite lengthy, for a crime novel, and it sometimes feels as though it's spending too much time wallowing in the depravity instead of getting on with the mystery. The depiction of Restoration London is one of the things which first interested me in the series, but I am feeling that by the fourth book it's becoming a little too much always the same.
Still, the characterisation is good, and the mystery is interesting and difficult to solve, and the historical background is meticulously researched. The ending is very good indeed. Generally, I felt that the positive aspects of The Westminster Poisoner outweighed the negative, though it is not as good as earlier books in the series where the background was fresher. My rating: 7/10.
