The Republic of Night — Dominic Martell

The Republic of Night finds Pascual still haunted by his past, as French intelligence agents locate him and make him an offer he can't refuse, to come to Paris and finger an old comrade, a long-disappeared Syrian terrorist who seems to have surfaced as a fixer for a shady Russian consortium. Pascual would just as soon not know what business the Russians have with a hatchet-face Algerian general who may be staging Islamist massacres in Paris to cover his tracks, but an exiled Algerian journalist wants him to help her find out. And Pascual, whose life is a continual process of atonement, knows he can't say no.
