A take-off of "Strangers on a Train". Like many small towns, the residents of Dale Falls have those among them that they like and those that they'd rather not have much to do with. When someone named the Chainmaster suddenly starts a chain letter asking a resident to permanently take care of someone else's problem. These residents start a murder spree affecting one resident at a time. Sort of "I promise to take care of your enemy, if you take care of mine".

As the body count starts to mount up, artist-turned amateur detective, Paul Marnay, starts to look into these mysterious deaths on his own. As he starts to turn up the heat on the Chainmaster, he suddenly finds himself a target.

Author Greenhall does a decent job moving the plot along as he introduces a lot of different characters. There's probably enough to keep most readers plodding along, but don't expect too much in the way of plot twists or surprise endings. ( )
