Clown Town (2025) is 9th in the Slough House series of books.

Like the rest, it’s worth reading for the outrageous behaviour of Jackson Lamb. And the smart, funny, cutting dialogue.

Plot? … well don’t worry too much about the plot in these books.

This time around, MI5 First Desk Diana Taverner tries to keep secret an old scandal that might come to light.

Jackson Lamb refuses to help. But his crew of Slow Horses somehow get involved anyway. Something to do with an old book of Cartwright’s grandfather.

In the end, Lamb takes action.

The TV series is better than the books. Season 5 is streaming now.
