Harold Warner

I couldn’t find a well-known novelist or author named simply Harold Warner matching a literary career (especially British). However, there is a notable writer whose full name includes Harold Warner:

H. Warner Munn (Harold Warner Munn)

Often cited as Harold Warner Munn (5 November 1903 – 10 January 1981), he was an American writer of fantasy, horror, and poetry.

Here is a sketch of his life and work — perhaps this is whom you meant:

Life & Background

• Born in Athol, Massachusetts in 1903.

• He died in Tacoma, Washington in 1981.

• Munn had a long but somewhat irregular literary career, writing in the pulp era and later returning to the field.

Literary Career & Achievements

Early Work & Pulp Magazines

• Munn published stories in Weird Tales, a prominent pulp magazine for fantasy/horror, beginning in the 1920s.

• His early notable story is “The Werewolf of Ponkert” (1925), which he wrote somewhat inspired by a suggestion from H. P. Lovecraft.

• That story spawned a series, Tales of the Werewolf Clan, which follows generations of werewolves and struggles with a supernatural “Master.”

Major Works: Merlin Saga & Others

• Munn also wrote a fantasy trilogy centered around Merlin and Arthurian themes:

  1. King of the World’s Edge (1939)

  2. The Ship from Atlantis (published later, 1967)

  3. Merlin’s Ring (1974)

  The first two were later collected under the omnibus Merlin’s Godson.

• His Tales of the Werewolf Clan stories were collected later in two volumes, e.g. In the Tomb of the Bishop and The Master Goes Home.

• He also wrote The Lost Legion, a historical / fantasy novel, and various poems (e.g. The Banner of Joan).

Style & Reputation

• Munn’s work is characterized by intricate plotting, elaborate mythic or supernatural elements, and a careful blending of research and imagination.

• Among peers and later readers, he gained renewed attention in the 1970s thanks to reprints in fantasy series (e.g. the Ballantine Adult Fantasy line).

• He was also known for being a cultivated collector of pulp magazines and classic speculative fiction.

Legacy & Influence

• While not as famous as some other fantasy authors, Munn’s work has a niche but loyal following among fans of classic fantasy and pulp literature.

• His blending of Arthurian myth, supernatural horror, and family saga has been admired for its ambition and imagination.

• The rediscovery of his works in mid-20th century fantasy reprint series introduced his work to new generations.

If by Harold Warner you meant someone else (British novelist, perhaps), I can dig further. Would you like me to check British literary databases or possible alternate names?
