Sam and Dean find an unlikely ally in the war against… library books. John Constantine? All he wants is a quiet life, but that's not the canon way, right? Rated T for adult themes, slightly horrific things that go om-nom-nom in the dark, sinister tones, a bit of rumpy-pumpy, and John's swearing.

Deaths of soldiers are haunting the newspapers - soldiers John knew from his former army company. Sherlock needs to find the serial killer before they can come for John, but the killer isn't human. They know this kind of case is not their speciality. If only they had a couple of friends who knew about this supernatural stuff. Oh wait; they do. Rated T for language and fights.
