A Good Yarn (Blossom Street, No. 2) by Debbie Macomber

London coroner Sir John Cranston and his faithful clerk, Brother Athelstan, return to pit their wits against a bloody murderer and the assassin in the House of Crows. It's the spring of 1380 and the Regent John of Gaunt needs money supplies for his war against the French. Unfortunately the members of parliament at Westminster are proving especially stubborn ndash; and the Regent's cause is not aided when some representatives from the shire of Shrewsbury are mysteriously murdered. John of Gaunt orders Cranston to find the assassin before he loses every chance of obtaining the taxes he requires. On top of that, Sir John and Brother Athelstan have their own problems. Someone is stealing cats from the streets and alleyways of Cheapside. And terrified parishioners are insisting that a devil incarnate is prowling around the parish of St Erconwald's, claiming innocent lives... The sixth tale in the Brother Athelstan series.
