Mark of a Murderer (Matthew Bartholomew Chronicle (Time Warner))

Matt and Michael are back for an eleventh misadventure involving the infamous St Scholastica's Day massacre in Oxford. A few months after this event some of the scholars have fled their town and come to stay in property owned by Oxford University in Cambridge. The town is getting spruced up for a visit by the Archbishop of Canterbury, but before the scholars have been in their new home a few hours two people are already dead. It seems as though they died in very bizarre circumstances, and if an even worse massacre is to be avoided, Matt and Michael had better get busy.
