SLADE HOUSE

Turn down Slade Alley - narrow, dank and easy to miss, even when you're looking for it. Find the small black iron door set into the right-hand wall. No handle, no keyhole, but at your touch it swings open. Enter the sunlit garden of an old house that doesn't quite make sense; too grand for the shabby neighbourhood, too large for the space it occupies.

A stranger greets you by name and invites you inside. At first, you won't want to leave. Later, you'll find that you can't.
