New York Oct 9 : If anyone has to be thanked for the long running Sherlock Holmes series, it is author Sir Arthur Conan Doyle’s mum, a new book on the writer-physician has revealed.

The tome ‘Arthur Conan Doyle: A Life in Letters,” that will hit bookshelves next month has some of the letters Doyle wrote to his mother.

In one such letters, the Scottish writer told his mum that he wanted to kill-off the detective.

However, his mother vehemently opposed his decision and asked him to continue writing more crime stories based on the brilliant London-based detective.

She also provided her author son with more plots.

The author wrote back to his mum telling her that he is continuing with the series, thanking her for the ‘en treaties’.

“(Holmes]) still lives, thanks to your en treaties,” the New York Post quoted him, as writing to his mother. (ANI)
