Generally, this had a good plot. Had there been some tightness to the story (perhaps told in one hour rather than an hour and a half) it would have worked better. In order to make this happen we had repetitive scenes and extended ones that did not move the story forward (e.g. All the singing at the dance club). It begins with what appears to be the deliberate asphyxiation by carbon monoxide of two young people. When a jogger finds the car, however, there is just the boy. The girl is nowhere to be found. This sends us on a merry chase. Where is the girl? Upon investigation, it is found the boy died of a blow to the head, not from the gas. It was murder. Now we have a parade of characters who knew the kids. A woman in an unhappy marriage. A pedophile photographer. The father of the boy, etc. Meanwhile, no one can figure out where the girl is. Barnaby figures there was a second figure in the car but has no leads. If this had just been a bit more compact and not so rambling, it would have been a much more interesting offering.
