After injuries to Barker in the last book, we find him still in the healing stages with a leg brace. By the end of this book he is ready to remove it. Llewelyn and his bride have happily adjusted to living in Barker's house after the renovations allowing them their own space on the fist floor.
A new set of problems brought to these inquiry agents result from a manuscript thought to be another gospel that has been stolen and is in high demand. The interested parties include the German government, a Count from Austria and the Vatican.
The Prime Minister asks Barker & Llewelyn to act as couriers to deliver the treasure to a representative from the Vatican. There is nothing straightforward about this assignment, of course. Most of the time Llewelyn is kept in the dark as to what is really going on as Barker keeps his plans to himself.
We are treated to secret societies, a revival meeting, sword fights with young German followers and political bickering between agencies and individuals. This is yet again a very satisfying episode in the Barker & Llewelyn Victorian London series.
