The darkness inside Francis' new friend Albie is bipolar. No matter how much he insists it's related to the moon, and he's actually a werewolf. Francis is a psychotherapist and social worker, and meets Albie at his job. He has mysterious problems that Francis recognises from professional experience.

Francis is already engaged. He has a nice safe life.

Even if Albie was a werewolf, Francis would probably know better than to get involved...
