The day of the black sun

A man washes ashore near an old couple's house, barely alive.

When he comes to, he has forgotten everything, including his name.

The only clues to his identity: a key sewn into his clothes, a bullet wound to the head - and the number XIII tattooed on his shoulder.

A meagre start to reconstruct one's self. Before XIII even begins to investigate, though, his past catches up with him, and it is anything but ordinary.

The trail is thin and the body count high, but XIII needs to know.

Even if, as the outlines of a massive conspiracy start to appear, some of the truths uncovered seem unpleasant.
