Geoffrey Mallory joins, with reservations, the ""desert paper chase"" of a Sir Max Lonsdale and Mallory is the only survivor of a native massacre which leaves him not only alive but with his hands on an unexpected Dead Sea Scroll. Faster than you can probably say Qumran, this proceeds to London where Mallory discovers that the Scroll is a reversal of the Judas Iscariot story, and to the Vatican where one of its members succeeds in executing others as well as his own mad design. A somewhat different, highly literate and patently exciting suspense story.
