The Fist was meant to end life on Earth—and someone on Earth was helping.

Investigative journalist Chloe Ashford has been tracing a philanthropic foundation's money and influence. Now the pattern is closing. Donations funneled through shell vehicles. Fellowship placements across policy, media, and defense.

On Mars, engineer Alexis Dren traces a single wrong digit in a weapons-system update to a coordination network buried inside his own command structure. One hundred kilometers of position error. A clean, deliberate, surgical betrayal.

A complex communications network between the alien intelligence that sent the Fist and someone on Earth. An alien plan and human collaborators.

Four investigations, two planets, four people who don't know each other exist. Each building the same case against the same man. Each closing on him from a different angle.

But Charles Haldane has been preparing for this for twenty-five years. He has a foundation, a fellowship pipeline, a senator, a street movement, and a concrete bunker in the Nevada desert. He also has something no one else knows about: a direct communication channel to the species that sent the Fist—and they are not done.

Satan's Hand is Book 2 of the Operation Clean Slate series. A political thriller built on real power, real conspiracy, and real consequences. The Fist missed its target. The aliens who sent it—and their collaborators on Earth—are not done.

With a Foreword written and read by Simon Edwards, President and Founder of SE Labs.
