Keane's Charge

The British and French armies have retreated from the city of Coimbra, leaving it in ruins. Infiltrating the streets are Spanish guerrilla fighters, local Portuguese determined to avenge the horrors inflicted upon them, and intelligence agents determined to find the hidden book of ciphers. James Keane and his men are sent into the midst of this, not only to prevent the book from falling into enemy hands but also to discover which of the guerrilla groups are to be trusted.
