The Invisible Code by Christopher Fowler

'The Invisible Code,' the 10th in Christopher Fowler's 'Peculiar Crimes Unit' series finds Detectives Bryant and May applying their unusual method of crime-solving in a baffling case involving international security issues and witchcraft. Arthur Bryant, the more eccentric of the two old detectives, brings his usual knowledge of London history and archaeology to bear on the case which somehow, circuitously, leads him to the answer. As usual at the very last moment, Bryant figures it out. The suspense about who done it and can they catch him continues to the last chapter. Fans will enjoy 'The Invisible Code'; newbies should start near or at the beginning of the series with 'Full Dark House.'
