Young secret agents can hone their skills with two titles. The Spy's Survival Handbook by Laban Carrick Hill, illus. by Robert Rath, provides techniques for surreptitious sleuths, from Braille, ASL and Morse codes for secret communication to tips on disguises, ciphers and shaking ""tails"" (""If a person keeps showing up, that person might be following you. Or, it could be your Mom""). The spiral-bound notebook features a mesh and bungee cover and a metal ""code machine"" for making simple alphabet-based secret codes.
