This adventure is in Signs and Portents issue 44 and I recommend it to anyone looking for good Conan scenarios. It could possibly be set in another city with ease but one thing I like about Vincent Darlage's adventures is that they give a sense of the culture of the area as per the REH setting. It has some very well developed NPCs in it and a clear plotline that could readily be improvised with depending on the inevitable fact that players often will do things you don't expect.
