Five Card Stud

After a cardsharp is caught cheating, he is taken out and lynched by the drunkards he was playing against. Soon afterwards, the men who were in the lynch mob start being murdered, one after another; all by hanging. Who will be killed next and who is responsible? Is it one of the original party seeking to cover their accursed deed, or perhaps the mysterious Rev Jonathan Rudd, who has recently arrived in town?
