This seemed, to all the world, like an ordinary flat in an ordinary apartment building in northern London, belonging to two young men. Nothing unusual about that. Even if the two of them often were outside of the city the majority of the time and there seemed to be no logical reason for them to be able to pay the rent on this place.
Except, this flat was leased to Samson Joshua Creed, known to the viceverse as SamJaz, the key-wielding hero that shoots himself in the head to make monsters appear, and he had an unusual roommate.
We won't go into what that roommate likes to call himself, because his name changes every week. We just call him Taylor.
