Clare College and King's College Chapel from the Backs

In the story… Spencer Cavendish has graduated from Trinity College at Cambridge in 1855. A year later he revisits his alma mater. He invites his sister, Louisa, and Diana to meet him there. Unexpectedly, he receives an invitation to High Table for lunch with a former professor and cannot join his guests right away. The women are left without a chaperone in what was then a male bastion. A situation arises that causes Spencer much anxiety for Diana.
