Platinum Rust by Andrew Gniadek

A heavy stench of burnt popcorn wafted off of the suspect as he was hauled into the station. Four dead men with a drunk suspect in custody. As strange as it seemed the main suspect was this one armed man. Lucky for them he is too tired to put up a fight. Soon enough they will find out how strange he is with the wild stories he tells them. They also find out how violently dangerous he is.
