The year is 1988, and the legendary detective Philip Marlowe finds himself seduced out of retirement by an enigmatic case that whisks him from the sun-soaked terraces of Baja California to the seedy underbellies of Mexico and California. Now seventy-two and accustomed to a quieter life of leisure, Marlowe is drawn into the death investigation of Donald Zinn, an American who allegedly met his end in the Pacific's unforgiving waters, leaving behind an alluring, yet possibly deceitful widow who has come into a considerable inheritance. The question of Zinn's fate and the true motives of those around him lead Marlowe into a labyrinth of greed, deception, and danger. With the same dogged determination that defined his career, Marlowe navigates a tangled web that may well be the seasoned sleuth's final mystery, 'Only to Sleep' seals Lawrence Osborne's homage to the works of Raymond Chandler with a story steeped in intrigue and nostalgia.
