Book One (the first 80 pages of 440) introduces the locale, the cast of characters, and a series of crimes: murders, stolen suitcases, an aborted espionage rendezvous, an escaped suspect. The descriptions are cinematic and the tone delightfully sardonic.
Book Two narrows the point of view to that of our amnesiac hero. The action remains vivid and the mystery of his identity is compelling, but the author isn't able to maintain the satirical tone. Most of the characters and investigations from Book One recede into the background. From this point forward, Sand is a (very good but) more conventional thriller, with a few descents into surreal comedy.
Sand would make an excellent limited series. It has an exotic locale, absorbing mysteries, and colorful characters. Adapting it, I would attempt to retain the tone and wider perspective of Book One.
