The Case

Six Dead. Somebody Stayed.

On the evening of 31 March 1922, all six people living at , an isolated farmstead in Upper Bavaria, were killed with a mattock from the farm's own shed. Then the farm went quiet, and for four days nobody came.

When neighbours finally forced the barn, they found something worse than the bodies. The cattle had been fed. Bread had been eaten, the stove used. . More than a hundred years later, nobody has ever been charged.

The full account — every footprint, every suspect, every myth checked against the surviving record — is in The Animals Were Fed, Book Six of The Unlucky Thirteen.
