This is a GREAT episode.  I think it is one of the BEST of the series.  It certainly is on my list of the top CBSRMT's best episodes. I enjoyed it so much I copied to a CD so I could hear it again whenever I wanted to.  The acting, writing, sound effects are  fantastic! When the demon that is possessing the son talks through him- his voice changes to such a demonic roar - it really creeped me out! I loved Joan Shay as the slightly intoxicated Irish cleaning woman!
