Biggles in the Blue
by W. E. Johns
Biggles travels to Jamaica to restore a cache of secret documents, projects of German secret weapons developed at the end of World War II. Their owner, Werner Wolf, lived in Jamaica for many years under a so-called name. Sadly, Wolf died without revealing where he hid his papers. There are a few tips to continue, just follow an oval shape with a small square on it. And Biggles must act fast because his old rival von Stahlhein, who now works for the Secret Service behind the Iron Curtain, is looking for the same thing in Jamaica.
