My rating: 4 of 5 stars
I picked this up for a pound in a charity shop in Caterham. I was surprised to find that it stood up well to the passing of time. It was written towards the end of the Spanish Civil War, during which it is set, and first published in 1939.
It still reads as a good story. A bit boys own in places, but it is Biggles and that’s exactly what Biggles stories are supposed to be. There is a good feel for the history, which is partly through being practically contemporaneous with the events it described. Well worth reading.
