The Lost Valley of Iskander

This is classed as a 'weird western', a mash up of two genres, actually three - a decent western story book-ending a zombie horror amidst a long and dreary sub-theosophical account of ancient depraved 'races' hurtling down the evolutionary scale.

Another work unpublished in his lifetime, this emerged for publication in 1967 and, frankly, was not really worth the effort. However, it made me want to read one of his straight Westerns - and I am not a fan of the genre.

There once was a time when Afghanistan was a remote country, little touched by the vicissitudes of global politics. It was also one of the few countries in the world not ruled by someone else’s empire. For Robert E. Howard, Afghanistan was a land where bold warriors lived and died by the code of the hills, an iron law of equal parts honor, loyalty, and revenge.
