Five Kentish knights gather annually at the Night in Jerusalem tavern in Southwark, a reunion of old soldiers. Good food, good drink, a doxy or two to hasten the blood, then back to their families. This year, though, is different, as one by one the knights are found dead, in mysterious and misleading circumstances.
Other murders occur, muddying the waters to be investigated by Sir John Cranston, Coroner of the City of London, and his scrivener Brother Athelstan. Underlying all is the tale of a stolen fortune, the Lombard treasure. Borrowed to pay for a war, gone missing with its escort on the night it was sent to a waiting fleet, many want the treasure - not least the Machiavellian Regent, John of Gaunt.
