Until episode 6 I thought it was great then it all went to pot with a rushed ending and more questions than answers. But no spoilers here. However, a few questions of note: How was a builder sourced, and able to start work immediately? Why were houses put up for sale within days of the murders? Why did police permit the murder house to go on the market whilst investigations were ongoing? What Estate Agent would allow viewings with blood all over the place? One neighbour thought a resident had moved out already and she explained "I haven't got a buyer yet" Why assume that getting a buyer means you take the cash say "thanks very much" and go, as if you'd just sold a pair of shoes? And what builder would install an island and start tiling a floor before the walls were completed? Why didJohn lose his temper and quit his job? This proved to be a red herring which made a change from all those magpies!! The first 5 episodes were excellent and I expected all the loose ends to be tied up in the anticipated instalment 6. But no.... what a let down. In hindsight, if I'd known how it would pan out I wouldn't have wasted 5 hours of my life watching it.
