‘Oh City of Dreadful Night!’ Athelstan whispered. The Dominican parish priest of St Erconwald’s in Southwark, secretarius atque clericus – secretary and clerk to Sir John Cranston, Lord High Coroner in the City of London – could only close his eyes and pray. Once again he and Sir John were about to enter the treacherous mire of murder. The hunt for the sons and daughters of Cain would begin afresh; God only knew what sinister paths their pursuit would lead them down. Athelstan’s olive-skinned face was sharp with stubble, his black-and-white gown not too clean, his sandals wrongly latched, whilst his empty belly grumbled noisily. The little friar, his dark eyes heavy with sleep, had been pulled from his cot bed by Cranston, who now stood behind him. The coroner had been most insistent. The Angel of Murder had swept The Candle-Flame tavern and brushed many with its killing wings. Edmund Marsen, his clerk, two whores and five Tower archers had been brutally murdered. The gold and silver, harvested south of the Thames and intended for the ever-yawning coffers of John of Gaunt had been stolen.
