Query: Another good work by Adcock.

The last book of the Hock series, "Grief Street", is a well-written thriller that ties up a few loose ends, and ends with hope restored to an area of Hell Kitchen. In this book, Hock tries to find a blaphamous killer, while dealing with some rogue "rapid" cops that hate Hock for telling on "King Kong" Kowalski. Kowalski himself finds that he finally has to come face to face with his demons. Finally, Hock finds the demented killer, and has a faceoff in a house with a bloody history, as an unexpected ally comes to his aid. Good finish.
