You never know what trouble will rise from the bog.

When the body of an unidentified woman is found in a Newfoundland bog, Inspector Danny Quirke must scramble his team of investigators to find her killer. But what initially seems like a straightforward case soon becomes mired in a tangled web of lies and deliberate obfuscation.

With the strange mutilation of the body—one eye gouged out completely—evidence seems to lead to a fringe religious group with bizarre beliefs. But while the pathologist indicates mushroom poisoning as the cause of death, Danny thinks circumstances point to something more sinister—especially when he begins to receive anonymous messages with links to horrific pictures of damaged human eyes.

Three more bodies join the first, with seemingly nothing to link them but a little girl in a yellow party dress who flits in and out of the mystery like a creature from the old legends. Then an old friend from his childhood reappears, and Danny is forced to confront uncomfortable truths about his own nearest and dearest.

On an island, everyone is a suspect…
