Single to Paris — Alexander Fullerton

A lone agent is sent into occupied Paris to find the mistress of a high-level Nazi officer in this edge-of-your-seat WWII espionage adventure.
 
When two agents are arrested in Paris, SOE agent Rosie Ewing is sent to rescue them. Also in Paris in the summer of 1945 is a woman called Jacqueline, already known to Rosie and now the mistress of a highly placed SD officer. Rosie's brief is to find Jacqueline, and through her discover where the two agents are being held -- then get them out before they either talk or die.

She needs help from the French Resistance. But both Gaullist and Communist groups are stirring -- and at each other's throats. There are also several exceptionally vicious pro-Nazi groups out there. Rosie is going in solo -- and virtually blind . . .
