I was three or perhaps four years old when I realized that I had been born into the wrong body, and should really be a girl.

The great travel writer Jan Morris was born James Morris. He distinguished himself as a wartime soldier and became one of the century's most daring reporters, climbing mountains and crossing deserts. To all appearances, he was happily married with several children.

But appearances can be misleading. James had known since childhood that at heart he was a woman.

Conundrum is the story of Morris' secret life and struggle for authenticity, as he embarks on experimental surgery to discover who he really is.

One of the first ever accounts of gender transition when first published in 1974, this is the blazingly honest account of perhaps Morris' greatest adventure: the decade-long journey to becoming a woman.
