'Jenny is horrified by the enormity of the situation. The virtual database which holds the vast quantities of Gatekeeper knowledge has been corrupted. Who can have infiltrated this, the most secret ancient Order? Or is it an inside job?
The young Gatekeeper sneaks back to Medieval England to investigate, but these are dreadful times. The Hundred Years War is raging in France and England is seething with treachery and intrigue. Jenny has to rescue a noble Earl from two attempted assassinations even when she, herself, becomes the suspect and suffers in the castle's torture chamber before she can escape.
During these travels through time, she observes one stranger who intrigues her. He has some understanding of magic but it was not derived from Jenny's evil nemesis from the past, Rudigor. In modern times Grimbald is a major player in a modern mob of German criminals called Die Kompanie - The Regiment. At the same time he plays an important role in a medieval regiment of Knights Templar. They are trying to find the location of tonnes of gold and silver stolen by the earlier brethren from the Al Aqsa Mosque on the site of the Temple of King Solomon. He is also behind the plots against the Earl of Norfolk and the person trying to save his life - Jenny.
What is Grimbald actually up to and has he been able to infiltrate the Gatekeeper ranks and corrupt their vital intelligence? It takes all Jenny's ingenuity to stumble upon the answer and when she finds it, it is totally unexpected.
