No case is too curious for Arthur Bryant and John May, London s most ingenious detectives. But with their beloved city engulfed in turmoil, they ll have to work fast to hold a sinister killer s feet to the fire. In the week before Guy Fawkes Night, London s peaceful streets break out in sudden unrest. Enraged by a scandal involving a corrupt financier accused of insider trading, demonstrators are rioting outside the Findersbury Private Bank, chanting, marching, and growing violent. 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 team are called in. Is this an act of protest gone terribly wrong?
