Patricia Highsmith's Hodmandod Tendencies.
This reminded me about a book I read in the British Library recently called Asperger's Syndrome and High Achievement by Ioan James (another title which tells you all you need to know) and it was a fascinating read. One of the people mentioned was Patricia Highsmith. There were few women in the book since Asperger's is more common in males. Patricia Highsmith seems to have been sexually ambiguous and, like all the other characters in the book, highly eccentric.
People with autism usually have social, speech and language impairments. They have repetitive routines, a strange sense of humour and tend to be clumsy. They also have all-absorbing narrow interests and Patricia Highsmith seems to have developed an extreme fondness for snails. Towards the end of her life she became a recluse and visitors described how she used to carry 100 snails around with her at a time. How, it does not say. But I imagine them forming a mobile armour, their constantly shifting shells making accidental patterns on her arms, their antennae stretching out whenever they sniffed green leaf. She would have to be careful how she sat... and it would explain why the snail mating scene in her short story was so well observed and sensuous.
