Almost two thousand years ago the silver shekels Judas was paid were re-forged as a dagger. When Masada fell the dagger of Iscariot and the truth of his sacrifice were lost. Now, a cult calling itself the Disciples of Judas has risen in the Middle East. In cities across Europe thirteen people martyr themselves in the name of Judas, promising forty days and forty nights of terror. Day by day the West wakes to harrowing acts of terror. As fear cripples the capitals of Europe, it is a race against time, as it is believed the terrorists intend to assassinate the Pope to bring down the Catholic Church. Sir Charles Wyndham's team of combat specialists, codename Ogmios, track a labyrinthine course from the backstreets of London...and into the heart of the Holy See itself.
