Crude Sunlight — Phil Tucker

The Buffalo State Asylum for the Insane is a grand and terrible building. Abandoned over forty years ago, its rooms and halls no longer ring with tortured screams.

When his younger brother goes missing, Thomas Verkraft comes to Buffalo to find him. Following a trail of black and white photographs and homemade videos, he tracks Henry down to the doors of the State Asylum.

It's the last building his brother entered before he disappeared.
