Thirteen steps down

A classic Rendellian loner, Mix Cellini is superstitious about the number 13.

Living in a decaying house in Notting Hill, Mix is obsessed with 10 Rillington Place, where the notorious Christie committed a series of foul murders.

He is also infatuated with a beautiful model who lives nearby - a woman who would not look at him twice.

Mix's landlady, Gwendolen Chawcer is equally reclusive - living her life through her library of books.

Both landlady and lodger inhabit weird worlds of their own.

But when reality intrudes into Mix's life, a long pent-up violence explodes.
