This novel reminds me a lot of Terry Gilliam's movie Brazil: a lowly clerk suddenly finds his world turned upside-down. A rather humdrum life has become a nightmare where nothing is as it seems: somewhere between dreaming and wakefulness, between reality and something you know is a dream, a trip on LSD. Unwin is a clerk--one of many in a huge room--on the 14th floor of the Agency. On the 29th floor is the person he clerks for, Detective Sivart. On the 36th floor is the Watcher Lamech, who oversees Sivart, and well below Unwin are the underclerks. Communications are all done through messengers. For anyone--clerk, underclerk, detective, or watcher--to be on the wrong floor of the Agency is a terrible and unthinkable breech. Everything is regimented--very regimented. Then Unwin's regimented life takes an abrupt upheaval.
Unwin is told that he's been promoted to Detective, and to move to Sivart's office on the 29th floor: Sivart has gone missing. Unwin reports to Sivart's boss, Watcher Lamech, only to find that Lamech has been murdered. So Unwin sets out to find Sivart, and you find yourself sucked into the whirlpool. Unwin meets the elusive Cleopatra Greenwood, Sivart's femme fatale (for lack of a more appropriate term for this very strange woman) and Sivart's archenemy Hoffman. The further you read, the more yu feel as though you've entered a hallucination. Everything is off-kilter: you enter a world of narcolepsy and somnambulism. Unwin follows somnambulists who go to the Cat & Tonic carrying bags of alarm clocks to gamble with. There's Caligari's Circus, taken over by Hoffman (Cleopatra Greenwood used to be a performer).
I don't think that there's any time in the novel where you have any idea at all what will happen next, but as things unfold they're either logically illogical or illogically logical--I think! If you like nice predictable novels, this definitely will not be your cup of LSD. This is very creative--bizarrely imaginative--and it had me turning quickly to Waitzkin's Attacking Chess and Guinn's new book on Bonnie and Clyde to try to unpretzel my mind. Think of the movie Brazil, or Jonathan Barnes' fine novel The Somnambulist, and toss in some LSD on top of those: a powerful and effective work!
