Taylor Caldwell – many great big books – “Dear and Glorious Physician” might ring a bell.
Denis Wheatley – quite a few dealing with the supernatural – “The Devil Rides Out” had me terrified for months!
James A Michener – his books were huge; many of them were made into movies; “Hawaii” being one of them. They were huge family sagas, involving many generations.
Wilkie Collins – the first author to write detective stories, notably “The Woman in White” and “The Moonstone”. Himself and Dickens were friends but he has been forgotten now.
James Clavell – I read and loved all his books; they were big books; I mentioned “Shogun” in the Large Books list. But they contained whole other worlds to get lost in and were so readable.
Somerset Maugham – he wrote many books and some became movies too – “The Razor’s Edge” and “Of Human Bondage” come to mind straight away. His short stories were unforgettable.
Graham Greene – again, many of his novels were turned into movies but no one seems to read the books any more, and they were great.
Frank Yerby – historical, colourful, and great fun, set in America’s deep south.
Maurice Walsh – the Irish writer from Kerry, responsible for one famous movie – “The Quiet Man”. It was a short story in a collection called “Green Rushes”. He wrote many books, all very romantic and all set in Ireland or Scotland.
Evelyn Waugh – who wrote “Brideshead Revisited” which was made into that wonderful, beautiful series. He also wrote many very funny books.
Henry James – I love Henry James; he’s old-fashioned of course but the novels are so good. Also made into many films – “Portrait of a Lady” “Washington Square” and “The Turn of the Screw”.
E M Forster – it’s becoming difficult to find an author whose books were NOT turned into movies! I’ll only mention my favourite one of his – “A Room with a View”.
D K Broster – no movies! He was a Scottish writer who wrote a trilogy of historical novels, all set in Scotland – very romantic!
I’ll just mention a couple of romantic novelists from my youth – I’m quite sure today’s young ones would find them hilarious: Denise Robins, Ethel M Dell, Barbara Cartland.
And a couple of detective writers – Dorothy L Sayers, Ngaio Marsh, Sir Arthur Conan Doyle, and Agatha Christie – does anyone read her books any more? So many glossy movies.
