Blood Covenant

You and your crew are hazmat cleaners on the night shift, taking contracts from a dispatcher who knows a lot more than he's telling you. The first job is Hargrove Psychiatric Institute, an abandoned hospital with a history nobody wants to talk about, and it won't be the last. On paper the work is simple enough: scrub the blood, seal the breaches and bag whatever's been left behind. The trouble is that every tool you use makes noise, the things in the building are listening, and something has moved in that leaves signs of its own. As the contracts keep coming, it becomes clear that Hargrove has roots reaching well past the hospital, out to an asylum, a farmhouse and the woods. The covenant demands blood, and it doesn't care whose.
