Dancing in Red

The prequel to Eilis Flynn and Heather Hiestand's Wear Black, "Dancing in Red" looks at how assassin Nellie Clifton started life:
She has bigger dreams than the Curragh - Nellie Clifton isn't going to spend her life as a “wren,” one of the prostitutes serving the soldiers on the desolate plains of the Curragh outside Kildare, Ireland.
The Prince of Wales is her escape plan - Nellie is going to make something of herself, and to do so, she has a plan: she is going to be the mistress of Queen Victoria's son, Prince Albert—but if he is a mistake, she needs another escape plan.
Her life is going to change in ways she could never have expected - Nellie Clifton: Well on her way to becoming a legend, instead of just a footnote in history!
