Whitsunday is the second instalment of 1588: A Calendar of Crime, a collection of short stories published in step with the sixteenth century calendar.

When a Lord Justice is found dead within the grounds of St Leonard's College an unfortunate group of students and teachers take it upon themselves to dispose of the body. However, when the supposed corpse vanishes from its hiding place it quickly becomes apparent that not all is as it seems at the College. Rumours of corruption, blackmail, murder and witchcraft begin to circulate as an invisible power struggle between rival colleges and a group of commissioners unfolds in St Andrews.

Before long, Hew Cullan and Giles Locke are reluctantly dragged into the ensuing melee of investigation and accusation. Hew must not only protect an innocent man accused of murder, but also salvage the teetering reputation of a respected commissioner.
