A woman's body is found in the Thames and she appears to be mixed up in a German spy ring. Major Ramsey is forced to call on Ellie's expertise when her uncle is unavailable. This is a decent historical mystery/espionage novel. I do still really love Ellie, her family, and Major Ramsey. However, the love triangle subtext is annoying. I'll keep going with the series, but I hope this nonsense of Felix vs Major Ramsey gets settled in book 3.
