Maeve Patricia Mary Theresa Gilmore (14 June 1917 – 3 August 1983) was a British painter, sculptor and writer, and the wife of author Mervyn Peake.

In 1981 she published a children's book, Captain Eustace and the Magic Room, that she had written and illustrated with dolls, working with artist Kenneth Welfare.

[11] On his death from dementia with Lewy bodies[12] in November 1968, Peake left a few pages of notes for a fourth book, of which fewer than a thousand words are legible.

[13] During the 1970s, Gilmore worked on the fourth Titus book herself, inspired partly by the list of people and places that Peake had imagined might feature in it.

[15] Early in 2010, Gilmore's children and grandchildren decided to publish it in time for the centenary of Mervyn Peake's birth in July 2011.

Of the various versions, they preferred one that made direct reference to the Titus books,[16] and arranged for the publisher, Vintage (in the UK; Overlook in the USA), to reprint Peake's notes as the first chapter.

[22] The Guardian called her "a shrewd and loving observer of domestic life" who "belongs in the company of women who deserve respect for their artistry, not pity for their disadvantages.
