Life in Baker Street is not all Nell Hudson thought it would be. The household is struggling financially, and in the masculine world of police work, Nell finds herself pushed aside in favour of Dr Watson. In search of money and recognition she takes a job as a department store detective.
Sherlock himself is busy investigating a missing prisoner; but when Emmett Stanley is found it turns out to be a case not of escape, but abduction. Then trouble strikes closer to home. Military secrets are being leaked, and Mycroft Holmes is under suspicion. When Sherlock tries to help, a rift opens between the brothers, and its consequences threaten Nell and Sherlock’s relationship.
In the midst of it all, an opportunity beckons for Nell. She is approached to go undercover as a spy; but to do so she must leave everything behind and live a life completely alien to her. Will Nell dare to step out of Sherlock Holmes’s shadow?
