"Treasure Trail"

I really like this cover, more so every time I come across it.  The story, according to John, is solid but doesn't stand out.  It does, however feature a couple of points of interest.  

The Black Ship, the notorious gangland dive, is visited in this story. That's noteworthy because it only appeared in two dozen of the three-hundred twenty-five Shadow pulp novels. And this was it's final appearance. After this, The Black Ship was mentioned no more.

Another note of interest is that when readers visit The Shadow's sanctum, they are given a description of how the master of the night exits his hidden den. On one side of the black room sits a huge metal file cabinet. The Shadow slides out the drawers, each automatically locks in a different position, forming a flights of steps leading upward. He climbs that improvised steel stairway, slides back a panel in the ceiling and passes through the secret exit. As the panel closes, the drawers of the filing cabinet glide soundlessly closed and the light is extinguished, all automatically. - The Shadow in Review

Enjoy, it's a 1937 tale so it'll not disappoint.
