Spearfinger is an SAS for Hunter: The Vigil. The story involves players investigating something that's harvesting organs from people.

Summary
From the Onyx Path catalog:


 * The old woman totters off to enjoy her breakfast, as tiny drops of bile patter on the street behind her.


 * People are turning up dead with their organs missing, but there’s no evidence of scars or surgery. The deaths are clearly unusual and perhaps even supernatural, and when one victim dies right in front of the hunters, their involvement becomes crucial. While the hunters may at first believe they are simply tracking down a monster, their investigations soon reveal a pattern to the killings, which implies some guiding intellect behind the travesties.


 * A story in the Storytelling Adventure System for Hunter: The Vigil.


 * Spearfinger contains Storyteller character records, relationship charts, a number of hyperlinks to various portions of the text as well as bookmarks, so you can always jump right to what you need with just a click. It is inspired and enriched by Witch Finders, but that book is not required to use Spearfinger.
