The eldest child of the Marquis and Marchioness of St. Aubyn’s, who own St. Aubyn’s abbey in London. He is the brother of Barbara, Clive, Michael, and Temple d’Orsey. Growing up, Clive is a close friend of Jamie Villiers, whom he rides horses with. Juliet believes that Clive and Jamie were emotionally (but not romantically) in love with each other, and Barbara is jealous of their relationship. Clive becomes a Cambridge poet and a soldier in World War I; his writing draws on his experiences in the war. On his leave, he comes to rest at St. Aubyn’s, which is converted into a convalescence hospital during the war. Here, he invites over a group of pacifist friends whose beliefs offend Michael. Once he returns to war, he is killed in the Somme offensive on July 1, 1916.
