- Reviewed in the United Kingdom on 2 July 2022I love this series and ordered the most recent book, the sixth, as soon as it came out. Master Mercurius, the narrator, is a complex and engaging character. The books are set in the late 17th Century Netherlands, among others in Delft and Leiden, both towns I know well and which are convincingly pictured. The latest book is partly set in the UK. Highly recommended! @delftbluebird
