Deaths Intertwined

Kay is an ex-cop, kicked off the force for disobeying direct orders...multiple times.
William is a retired marine.
Together they make the best private detectives New York - er, the Lower East Side - has ever seen.

Kay promised that they would never investigate another murder. But when her sister turns up dead, sitting in a pool of blood at her kitchen table, the pair have no choice but to take the case.
