Enraged by a scandal involving a corrupt financier accused of insider trading, demonstrators are rioting outside the Findersbury Private Bank. But when someone hurls a Molotov cocktail at the bank’s front door, killing a homeless man on its steps, Bryant, May and the rest of the Peculiar Crimes Unit is called in. Is this an act of protest gone terribly wrong? Or a devious, premeditated murder? Their investigation heats up when a second victim is reported dead in similar fiery circumstances. May discovers the latest victim has ties to the troubled bank, and Bryant refuses to believe this is mere coincidence.
