Robert Amiss finds himself involved in a murder case – not as a suspect because he couldn’t have murdered the victim – but as a mole helping Superintendent Jim Milton to understand the background to the case. Amiss is a civil servant working in Whitehall and Sir Nicholas, his boss, is murdered. The problem is that just about everyone who was involved in the meeting just before the murder had the means, the motive and the opportunity to commit the crime. Milton finds himself at a loss when it comes to understanding the civil service culture and Amiss agrees to help.This is a well written murder mystery with an interesting and authentic background with many amusing moments. I first read this book some years ago and I found it just as good on second reading. It is well plotted with believable and likeable characters. The book is the first one in a series and more series characters are introduced in later books.
