The great Mordecai moustache mystery - Kyril Bonfiglioli

Kyril Bonfiglioli's final novel follows the Hon. Charlie Mortdecai from adventure to misadventure via Jersey and Moscow to a final showdown in a Buckinghamshire bungalow of unparalleled hideousness. Tackling en route an unhealthy sprinkling of well-seasoned academics, a cryptic monk, an aristocratic Chief Constable, and more spies than you could shoehorn into a black stretch limo, Mordecai finds himself embroiled in another mission of international insecurity.
Left unfinished at the time of the author's death, the celebrated satirist and parodist Craig Brown supplies the penultimate, plot-resolving chapter.
