Reg Ex Help - Copy to Series Field

Hi:

Please forgive my ignorance, I have searched the help file and the forum but I cannot seem to find help with what I need. I have the following data in my Title field, but I would like to move the series information from the series field and into the series field, is this possible with Regex? If so, can someone help me set it up? This is what the field looks like:

Dead Silence (The Body Finder, #4)
