Conan Doyle's Casebook Welcome to the official page for the Sir Arthur Conan Doyle Collection (Richard Lancelyn Green Bequest).

Here you'll find out all the latest news, events, exhibitions and information. The Conan Doyle Collection was bequeathed to Portsmouth City Council in 2004 in the will of Richard Lancelyn Green, perhaps the world's foremost collector of material related to Arthur Conan Doyle and his literary creations, the most famous of all being Sherlock Holmes

It is now split between the museum, library and archives in Portsmouth, featuring a permanent exhibition, a vast collection of books and over 1,000 boxes of archival material. The exhibition is open free to the public at the Portsmouth City Museum 7 days a week, and the public will soon be able to access the archive in the new research room due to open in early 2011

We are looking for ward to Anna Behrens talk on the 23 June at 7pm (UK time)

Jean Leckie From Mistress to Medium

Arthur Conan Doyle was immediately attracted to young and attractive Miss Jean Leckie, whom he met at a party while his wife Louisa was bedridden with advanced Tuberculosis. Conan Doyle and Jean grew close and secretly spent time together. When Louisa died years later, Conan Doyle married Jean and they had three children together. Jean changed from a non-believer of Spiritualism to becoming the family Medium. She then, through a spirit guide named Pheneas, advised Conan Doyle on many aspects of his life. Just how far did Lady Jean go in manipulating her besotted husband?
