Murder strikes at the heart of Oxford's academic world when a retired university fellow is cold-bloodedly stabbed to death. A complicated investigation uncovers undergraduate suicide, drugs in the college and the subsequent dismissal of a loyal college scout. Suspects abound and so do their alibis. Then a ceremonial knife goes missing from a museum and a body is washed up on the banks of the river Cherwell. Featuring Tony Haygarth (Our Friends In The North, Bramwell).
