WHILE Bolton waits to see how much cash it can make by flogging Millais’ painting The Somnambulist, I have been reading the debut novel with the same title written by a Victorian enthusiast, Essie Fox.

The painting, which is being auctioned in London next month and expected to realise between £70,000 and £100,000, helped to inspire the book and is copied on the first page.

I started to read the book (after I was sent a copy by publishers Orion Books) with a passing professional interest, but eventually I was hooked on this wellwritten tale taking in Victorian sleep-walking, lost love, murder and madness.

Many people thought Millais’ painting was based on Wilkie Collins’ novel, The Woman in White.

Others presumed it was Bellini’s La Sonnambula — a popular 19th century opera.
