Cleeve is the eldest son of Edward Elmes Cleeve, an English immigrant, and Sophia Journeaux, whose family came from Ireland.
In 1860, Cleeve travels to Ireland to stay with his mother’s relatives who run an agricultural machinery business in Limerick known as J.P. Evans & Company. He decides to remain in Ireland and eventually assumes control of the business.
Cleeve marries Phoebe Agnes Dann in 1874 and they have five children. The author and broadcaster Brian Cleeve is his grand nephew.
In 1883, Cleeve starts a new enterprise, the Condensed Milk Company of Ireland, in conjunction with two local businessmen. The company manufactures dairy products, such as condensed milk, butter, cheese and confectionery. Its headquarters are located in Limerick city, on the northern bank of the River Shannon. The business expands over the next 20 years to become the largest of its type in the United Kingdom.
Cleeve is also senior partner in the Cleeve Canning and Cold Storage Company based in British Columbia. He is also the President of Limerick Chamber in 1908-09.
In 1899, Cleeve is voted onto the Limerick City Council. That same year, his fellow councillors elect him as High Sheriff of Limerick City, the Queen’s representative in the city. He holds the position again in 1907 and 1908.
In December 1908, Cleeve is taken ill at a public function. Despite undergoing surgery, he dies of peritonitis on December 19, 1908, at the age of 64. According to contemporary newspaper reports his funeral is one of the largest seen in Limerick city, with crowds lining the streets up to an hour before the cortège passes. He is buried in the churchyard of St. Mary’s Cathedral in the city.
Cleeve is the second of three sons to Charles Edward Cleeve and his wife Josephine (née Talbot). His father, who was born in Limerick, County Limerick, is a scion of a famous and wealthy family that runs several successful Irish enterprises in the late-nineteenth and early twentieth centuries. His mother is a native of Essex. The Cleeves came from Canada originally and emigrated to Ireland in the mid-nineteenth century. As a result of labour troubles and the effects of the Irish Civil War, the Cleeve business fails, and the family moves to England.
Cleeve’s mother dies in 1924 and his maternal grandparents, Alfred and Gertrude Talbot, take over responsibility for his upbringing. At age eight, he is sent as a boarder to Selwyn House in Kent, followed at age 12 by three years at St. Edward’s School, Oxford. He is by nature a free-thinker and rejects the assumptions and prejudices that are then part of upper-middle class English life. His unwillingness to conform means that school life is very difficult for him. In the late summer of 1938, he decides not to return to St. Edward’s for his final year. Instead, he runs away to sea.
In 1945, Cleeve takes an Irish passport and comes to Ireland where, in the space of three weeks, he meets and marries Veronica McAdie. A year later, they leave Ireland with baby daughter Berenice on a protracted odyssey that takes them to London, Sweden, the West Indies, and finally South Africa. In 1948, the family settles in Johannesburg where they set up their own perfume business. A second daughter, Tanga, is born to the couple there in 1953. As a result of his friendship with Fr. Trevor Huddleston, he witnesses the conditions in which the black population has to live in townships such as Sophiatown. He becomes an outspoken critic of Apartheid, and, in 1954, he is branded by the authorities as a ‘political intractable’ and ordered to leave South Africa. He returns to Ireland where he lives for the remainder of his life.
Cleeve starts writing poems in his teens, a few of which are published in his school paper, the St. Edward’s Chronicle. During the war he continues to produce poems of a spiritual or metaphysical nature, most of which are never published. In 1945, he turns to novel-writing. After his first two attempts are rejected, his third novel, The Far Hills, is published in 1952. Two further novels about South Africa follow and their unvarnished descriptions of the reality of life for the native population probably contributes to his eventual expulsion from the country.
In the mid-1950s, Cleeve begins to concentrate on the short story form. During the next 15 years over 100 of his short stories are published in magazines and periodicals across five continents. He sells nearly thirty to The Saturday Evening Post alone. In 1966, his story Foxer is honoured with a scroll at the annual Edgar Awards.
During the 1960s and 1970s, Cleeve returns to writing novels with considerable success. He produced a series of well-received mystery and spy thrillers that do not sacrifice character to plot. In 1971, he publishes Cry of Morning, his most controversial and successful novel to date. It is a panoramic depiction of the economic and social changes that affected Ireland during the 1960s as seen through the eyes of a disparate collection of well-drawn characters. He subsequently achieves even greater commercial success, especially in the United States, with a number of historical novels featuring a strong female character as protagonist.
Cleeve also writes several works of non-fiction, principally the Dictionary of Irish Writers. This is a 20-year project to provide to scholars and the general public alike a comprehensive resource on Irish writers at an affordable price. It is a labour of love that consumes a great deal of his time and is effectively subsidised by his more commercial pursuits. The last edition is published in 1985.
On December 31, 1961, Telefís Éireann is launched as the Republic of Ireland‘s first indigenous television station. Cleeve joins the station as a part-time interviewer on the current affairs programme, Broadsheet. Following appearances on two additional programmes, Telefís Éireann does not renew his contract when it expires in 1973.
Following his wife’s death in 1999, Cleeve moves to the village of Shankill, Dublin. His health deteriorates rapidly following a series of small strokes. In November 2001, he marries his second wife, Patricia Ledwidge, and she cares for him during his final months. He suddenly dies of a heart attack on March 11, 2003. His body now lies under a headstone bearing the inscription “Servant of God.”
