The documentary series which explores some of Ireland's most high-profile murder cases returns this evening, and we're delving right in at the deep end. Pensioner Eddie Fitzmaurice was beaten and bound in his bedroom in Co Mayo back in May of 1988. The old man tried to seek out help, but froze to death as he tried to signal for help. Be prepared for things to get just as heavy throughout the series, as we see a darker side to our little island.
