Robert Urich played the character as a tough detective with a soupcon of guy nextdoorism that gave it a little difference from the other similar type dramas on television. Unfortunately this season two of the female characters (Angie and Sargeant Bella Archer) from Season One are gone. Keep your eyes open for guest appearances from the likes of Shelley Winters, Gary Collins, Minnesota Fats, Eve Arden, and Melanie Griffiths.
