May 1942. In the sands of Libya, soldiers discover a tomb containing a crown of thorns and the devastatingly powerful Spear of Destiny. They've found the last resting place of Christ. Sixty years on, Gerald Usherwood and his old army pal Max 'Chips' Chippendale pay the ultimate price for the secrets they stole. Gerald, his throat slashed, is nailed to the wall in a crude impersonation of the crucifixion, and his old friend suffers a similar fate. Gerald's grandson DCI Ethan Usherwood is left to piece together the mystery behind the killings and uncover the treasure hidden for so many years.
