Peake was writing a fourth novel, "Titus Awakes" at the time of his death, which was later completed and released by Peake's widow in 2009. Gretchen Osgood Warren (19 March 1868 – September 1961), the wife of Fiske Warren, was an actress, singer and poet.  The daughter of Dr. Hamilton Osgood and Margaret Cushing Osgood of Beacon Hill, Boston, Massachusetts, her younger sister was Mary Alden Childers, the wife of writer and Irish nationalist Robert Erskine Childers.  Her nephew Erskine Hamilton Childers served as the fourth President of Ireland from 1973-74.

He was the eldest son of Erskine Hamilton Childers (Ireland's fourth President) and Ruth Ellen Dow Childers.

The book, which enjoyed immense popularity in the years before World War I, is an early example of the espionage novel and was extremely influential in the genre of spy fiction.  It has been made into feature-length films for both cinema and television. Robert Caesar Childers (1838 – 25 July 1876) was a British Orientalist scholar, compiler of the first Pāli-English dictionary.  Childers was the husband of Anna Barton of Ireland.

Robert Erskine Childers DSC (25 June 1870 – 24 November 1922), universally known as Erskine Childers, was a British writer, whose works included the influential novel "The Riddle of the Sands", and a Fenian revolutionary who smuggled guns to Ireland in his sailing yacht "Asgard".  He was executed by the authorities of the nascent Irish Free State during the Irish Civil War.  He was the son of British Orientalist scholar Robert Caesar Childers; the cousin of Hugh Childers and Robert Barton; and the father of the fourth President of Ireland, Erskine Hamilton Childers. Mervyn Laurence Peake (9 July 1911 – 17 November 1968) was an English writer, artist, poet, and illustrator.  He is best known for what are usually referred to as the "Gormenghast" books.  The three works were part of what Peake conceived as a lengthy cycle, the completion of which was prevented by his death.  They are sometimes compared to the work of his older contemporary J. R. R. Tolkien, but his surreal fiction was influenced by his early love for Charles Dickens and Robert Louis Stevenson rather than Tolkien's studies of mythology and philology. Boy in Darkness is a novella written by Mervyn Peake.  It was first published in 1956 by Eyre & Spottiswoode as part of the anthology "Sometime, Never: Three Tales of Imagination" (with other stories by William Golding and John Wyndham).  A corrupt version of "Boy in Darkness" was published both in an anthology, "The Inner Landscape" (1969), and separately in 1976 with an introduction by Peake's widow, Maeve Gilmore.  Referring to the corrupt text, she wrote that "although the Boy in "Boy in Darkness" is assuredly Titus Groan, [Peake] did not call him so by name"; however, adding the name Titus was one of the specific changes that Peake made between writing and publishing his novella.  The correct text has recently become available again in an anthology entitled "Boy in Darkness and Other Stories", with a foreword by Joanne Harris and a preface by Peake's son Sebastian, as well as Maeve Gilmore's uncorrected introduction from 1976.
