What metaphors are used in The Fall by Albert Camus?

In describing his law practice, Clamence refers to himself as a deus ex machina - a figure in ancient Greek and Roman theatre that would be lowered to the stage by means of a crane in order to restore order and to pronounce the play's final outcome. He claims this role for himself as an accurate metaphor of his work with the demoralized criminals of Paris. These men - many of them murderers - become criminals in response to the anonymity conferred by modern society. They are desperately searching a way of distinguishing themselves from the rest of nameless citizens. Clamence seeks a similar satisfaction but, rather than commit a single crime which will soon be forgotten, he remains constantly attached to crime - reaping its dubious rewards - but out of the reach of retribution.
