"Hello, Peter." The words were a low, deliberate purr in the stale, fluorescent-lit office. Mark Hoffman watched, a predator's grin playing on his lips, as Peter Strahm's mouth tightened into a silent, furious line.

"We're tracking a killer together. Surely we can drop the formalities?" His eyes lingered on Peter's hand, the knuckles bone-white where they clenched a pencil, and he felt a familiar, dark thrill.
