The Stonemason's Tale: Oxford Medieval Mystery Series, Book 6 (Unabridged‪)‬

Oxford, Spring - 1354. 

When the series of accidents to the building of the chapel at Queen’s College begin, they do not appear a cause for concern, but they grow more serious, and stonemasons are injured. Nicholas Elyot becomes involved after it is discovered that an intruder has reached the college by way of his garden. When Jordain Brinkylsworth’s youngest student goes missing, it seems at first that his disappearance is unconnected, yet he is one of the ‘poor boys’ supported by Queen’s. Surely this serious and studious boy cannot be responsible for the troubles? 

And then someone is killed.
