The Mark of a Murderer

February 1355: Oxford explodes in one of the most serious riots of its turbulent history. Fearing for their lives, the scholars flee the city, and some choose the University at Cambridge as their temporary refuge. But they don't remain safe for long. Within hours of their arrival, the first of their number dies, followed quickly by a second. When Matthew Bartholomew begins to investigate the deaths, he uncovers evidence that the Oxford riot was not a case of random violence, but part of a carefully orchestrated plot.
