At his house in
Portman Square, London, the famous poet Oliver Blayds is celebrating his 90th birthday. The literary critic A. L. Royce has come to present an address on behalf of his fellow writers to Blayds, who is regarded as "a very great poet, a very great philosopher and a very great man … simple as
Wordsworth, sensuous as
Tennyson, passionate as
Swinburne". Royce has lingering feelings for Isobel Blayds, whom he met 18 years earlier when they were both about 20. She declined his offer of marriage then because she felt she must look after her father. The poet's grandchildren are cheerfully indifferent to his literary reputation, and treat him with affectionate irreverence, to Royce's disapproval. The family gathers, and after his health is toasted Blayds graciously accepts the address from Royce. He reminisces about his earlier days in Victorian times with anecdotes about
Browning,
Whistler,
Queen Victoria and
Meredith. After the celebrations, Blayds is left alone with Isobel, who has looked after him all her adult life. He says at ninety there is no going back: "Only forward – into the grave that's waiting for you". In the second act the family returns from Blayds's funeral at
Westminster Abbey. Isobel reveals that on his deathbed Blayds confessed to her that none of the poems for which he is famous were written by him. They were the work of Willoughby Jenkins, a close friend with whom he shared rooms in
Islington in the 1850s. Jenkins, a young poetic genius, knew he was dying and wrote a prodigious amount of poetry while he had time. After he died, Blayds yielded to the temptation to publish a small amount of Jenkins's verse under his own name. It was so well received that he continued the deception and published further batches over the years, gaining a tremendous literary reputation and making a large fortune. The one volume he published of his own verse had been badly reviewed and otherwise his entire poetic oeuvre was the work of his dead friend. Isobel is bitter at having given up any independent life to look after her fraudulent father. William, who hero-worshipped his father-in-law, is incredulous, and agrees with Oliver that Blayds must have been hallucinating on his deathbed. The family agonise about whether the confession is true, and if so whether to reveal the truth publicly, and whether the old man's fortune properly belongs to Jenkins's heirs. Royce, to whom Isobel has turned for help, finds documentary proof that Jenkins left everything he had to Blayds. The family is legally in the clear, but the moral issue remains. William continues to maintain Blayds's innocence, and Isobel eventually gives way and agrees to say nothing publicly about her father's confession. At the end of the play she accepts a proposal of marriage from Royce. ), Marion (
