With advice on its plot and characterisation and praise for its "zest" from Neil Munro, the novel My Lady of Aros was published in 1910.
In 1923 he published the novel The Captain More, a re-working and extension of the ideas of his play Glenforsa.
Perhaps, outside his plays, the most interesting achievement of his later literary work is his third and final novel Strawfeet (1930).
This deals with the First World War and is set partly on Mull and partly in France on the Western Front.
Like My Lady of Aros it deals again with espionage and betrayal but this time in contemporary life.
Brandane is one of the few Scots to have written a novel dealing with the First World War. In 1935 he found the demands of medical practice in the city and authorship too heavy. He returned to the Highlands to rural practice in Lochgoilhead in Argyll. He died there on 17th October, 1947.

John Brandane (the pen name for Dr John MacIntyre) was arguably Scotland's best known resident dramatist in the 1920s before the emergence of that other great doctor/dramatist James Bridie (O. H. Mavor).
He was born in Rothesay on the Isle of Bute on 14th August, 1869.
His family moved to the Bridgeton area of Glasgow and as a boy he worked in a Glasgow cotton mill.
Between the ages of 15 and 27 he was employed as a clerk in a warehouse.
During his latter years in the warehouse he took up the study of medicine at Glasgow University.
In 1901 he graduated and while specialising in surgery at Glasgow Royal Infirmary he met and became a friend of Bridie.
In 1935 he found the demands of medical practice in the city and authorship too heavy. He returned to the Highlands to rural practice in Lochgoilhead in Argyll. He died there on 17th October, 1947.
