The year is 1928, the heyday of the Roaring 20's.
Prohibition is the thing, rum-runners are making dough, and the head of the Chicago Outfit runs the city.
Sylvia and Welsh, the two ladies of what would eventually become Silken Whispers Artefact Recovery Agency, race against each other in an effort to find the hidden vault of Al Capone. With the promise great wealth for the risk, they follow rumors of an unknown but mystical treasure locked away inside the secret vault. The women go head-to-head against the brutal thugs of Prohibition gangsters, a secretive branch of the US Government, and ultimately each other.

What was an already almost impossible theft from a gangster's headquarters becomes much more deadly as the Hidden World reaches out to touch their souls. They are forever changed when the shadowy realm of mythology and the supernatural rears its ugly head in this tale of these women's violent first meeting, how they became who they are, and the launch of over eighty years of globe-trotting daring-do adventuring.
