The Hidden

British author Hill's fourth novel, a chilly existential thriller, is dazzling in places, but suffers fatal problems of pacing and plausibility. Ben Mercer, a disaffected Oxford classics student, runs off to Greece to escape the fallout of a failed marriage. There, a chance encounter with former colleague Eberhard affords Ben the chance to work on an archeological dig in Sparta, Spartan civilization being Ben's area of expertise (his “Notes Towards a Thesis” on Spartan culture are interspersed throughout the novel and make a fascinating parallel text). Ben receives a frosty reception from Eberhard's secretive group, but after finding deformed skulls at the dig site, participating in a jackal hunt and developing a relationship with the beautiful Natsuko, Ben is accepted and begins to realize his compatriots have a sinister agenda. Hill's use of the thriller structure to make broader commentary about modern life provides many rewarding and intelligent turns, but the plot itself is slow, predicable and, due to the villains' largely unexplored motivations, unsatisfying. The evocations of Greece and historical details of Sparta are excellent, but too much of this novel is muddled or at odds with itself. (Oct.)
