The Open Door

By John Moloney

They waited four days to call him.

Luca Donati is a functional component of a system that no longer officially exists. Laicised by the Church for knowing too much, he now operates as an independent threshold-holder - addressing structural failures in the boundary between the living and the dead.

When a Rome investigation reveals a pattern of mechanical decay across the city's oldest ecclesiastical buildings, Donati recognises something he has seen before - the specific signature of a Breach that has been left open too long. Something has been using the interval. Practising.

The Open Door is the first book in The Vatican Demonologist Files - a slow-burn institutional thriller for readers of Umberto Eco and John le Carr . No spectacle. No salvation. Just the cold arithmetic of a failing system, and one man whose survival of a 2003 cardiac event made him a necessary component of it.
