Narrative:

I was PIC flying an A36 bonanza to hollister with [another pilot] sitting in the right seat. [He] is a certified pilot.we were approaching hollister airport (cvh) from the north and entered on a left downwind for runway 31 and announced our position on CTAF. The only other planes on frequency were a helicopter doing pipeline work west of the field at 300 feet and [another aircraft] getting ready to takeoff.as we entered the downwind; [right seat pilot] and I noted an aircraft departing runway 31. It did not make any radio announcements on CTAF. I announced my position throughout the pattern. There were no communications from other airplanes in the pattern. We set up for a normal approach. We turned final and the [other aircraft] was holding short of runway 31.as we were on final at approximately 500 feet AGL; the pilot of the [other aircraft] announced that there were two planes on final. I looked up and observed another bonanza right above us on approach for the same runway approximately twenty to thirty feet above us and slightly in front of us. I immediately began a turn to the right and initiated a go around; parallel and east of the runway. As I was in my upwind; I remained east of the runway; and observed the other bonanza climbing off runway 31 parallel to us. No communication from the other bonanza was made throughout the incident. He proceeded to fly straight out parallel to us. The helicopter made a radio call saying that there were two airplanes flying parallel to each other on upwind; and I responded that the other airplane was not on frequency; but I had them in sight. I proceeded to turn crosswind behind the bonanza and re-entered the pattern. We did not see him again.

Title: Reports from two light aircraft pilots involved in an NMAC in the pattern at CVH. Improper communication on CTAF frequency was reportedly a factor.
