Once a penniless orphan, Scuff is studying medicine at a free clinic run by Dr. Crowe. But lately Crowe has been distracted, having witnessed an altercation between a wealthy former patient of his named Ellie and her controlling fiancé. It seems that someone is forcing Ellie to marry the man. So Crowe sets out to uncover the troubling connection between Ellie, her father and her betrothed. With Crowe engrossed in his investigation just weeks before the holidays, Scuff is left to run the clinic on his own, treating London’s poor and vulnerable. In the holiday spirit, he offers Mattie, a young girl in need, a warm place to stay as the winter chill sweeps through the city. Together, Scuff and Mattie also must fend off the police, who are growing suspicious of Crowe’s amateur sleuthing.
