The perfect couple. The perfect house. The perfect crime.

Londoners Jack and Syd moved into the house a year ago. It seemed like their dream home: tons of space, the perfect location and a friendly owner who wanted a young couple to have it.

So when they made a grisly discovery in the attic, Jack and Syd chose to ignore it. That was a mistake.

Because someone has just been murdered outside their back door. And now the police are watching them.

This story is their chance ...

To prove they're innocent.

Or to get away with murder.
