The story begins with a Yuetshi man deposited on the coast of Xapur, an abandoned island, after a storm disrupts his fishing. When exploring the island, a thunderous boom echoes causing the man to go investigate the source of the sound. He stumbles on a large domed structure that has been broken open. Inside, the man tries to take a shiny dagger from a giant corpse (mummified?). The corpse awakens and kills the man.
Like a lot of Conan stories, there's a political war waging. A lord by the name of Agha is ordered by Turan's king to quell a recent uprising near the border. A team of guerrilla fighters, made up of kozaki bandits, is pillaging Turan's interior. Their leader is Conan. An elaborate trap is formed that places a young maiden named Octavia on the abandoned island of Xapur (the one now housing a giant!). Here, they will lead Conan to Octavia in a snare that will allow Agha and his soldiers to hunt and kill the barbarian. It sounds way more complicated than it really is, but there are numerous plot holes here that Howard doesn't shore up.
Off-page events transpire and the trap is in motion. Octavia is on the island. Conan sails to the island. The two run into the giant. Fairly simple. Conan quickly learns that the giant is made of iron (thus the story title) and that he will need something other than brute strength to outwit the behemoth. By the story's end, Conan has “taken” the girl's kisses and makes a path to lead her to his tent. Maybe they will make marshmallows?
If you can sense my tone, this wasn't one of my favorites Conan stories authored by Howard. The abandoned island producing a city was really bizarre and felt rushed. I'm not sure if the “Dagon” featured here has any connection with H.P. Lovecraft lore, but this Dagon is the name of a city, not a deity. The giant's colossal nature, or threat, didn't seem to affect me much after reading Conan's battles with far more menacing beasts. This was a boss-fight that didn't quite pan out. I recommend a pass on "The Devil in Iron".
