The Mafidon Inheritance

The only known clue to a rare historical artifact that has been missing for over three hundred years is an ancient bronze collar kept in a vacuum-sealed hyperbaric chamber that went missing in a large warehouse full of suspicious personnel. It becomes a race against time to find the chamber before accidental exposure to the air.

In desperation, the chamber owner, from a criminal gangster family, abducted a man in a ruse known to be the cousin to the suspected thief.

The pursuit lands in Africa, draws in the British secret service, MI6, and back to a warehouse identified as a den of terrorists in East London.
