For PIs Michael McCree and Simon Hart, life has become…if not humdrum, then unusually calm. Routine cases, daily training with their band of back-street urchins, the incessant games of sex and innuendo—all of it takes on a keener edge when they learn that an arch enemy has somehow slipped through a crack in Ireland’s notorious Old Chokey Prison. Instead of quietly leaving the country, their implacable opponent is out for blood…namely, the blood of two sleuths named Michael and Simon. The enemy is desperate, and greedy too. Some of the the ones fighting alongside the PIs are excellent, some are rather good, and a few are outright dishonest. Nothing stirs their imagination and, um, base instincts like raw danger. Both men find themselves sliding into more than one crack in the Roaring Twenties city of Dun Linden as they alternately evade and pursue, duck and dodge, parry and thrust—starting in the bedroom of their own Victorian flat.
