I've been super interest in Bryan Charles Waller and his role in the Doyle family, and as a result I've been going back over everything about Charles Altamont Doyle. CAD was a severe alcoholic, and from 1885 onwards was in permanent care till his death in 1893. CAD was a draughtsman by trade and an artist, and he executed illustrations for both 'A Study in Scarlet' and 'The Mystery of Cloomber' while in Montrose Royal Lunatic Asylum (Sunnyside).

While in Montrose, CAD also created what is believed to be a series of artistic notebook. It is suggested these were partly created to demonstrate that he was not insane. Only one of these notebooks remains, covering about three months in 1889, and was discovered in the 1970s. Sherlock enthusiast Michael Baker published the notebook.... I'm assuming it was then broken up to sell. individual leaves (I might be wrong).

Two things ; CAD regularly draws angels over people (including himself) and regularly expresses the feeling or with that he'll be free / dead soon. So sad.

One little sketch along this line intrigued me, with a note next to it:

'Come home'

NOTE: That Book he has got is the "Ursuline Manual", and has been his best friend. The Ursulines are a community of Nuns in Ireland where this valuable book was compiled. 7th June 1889.

And when we look at the Ursuline Manual (1855) what do we see? 

Where is home? A house in Edinburgh that he may not know no longer contains a family? Heaven? Ireland? To wherever his wife is?
