This serial continues with evidence coming down stronger on the side of this all being a Scooby Doo plot, with a rich developer called Mr. Dove – that guy in the high rise we saw last time – hiring the dirty musicians to mess with the barely-making-ends-meet people who run the market stalls. This has all been clearly designed from the appearance backward. The scruffy villains are threatening because they’re so peculiar. In a less far-out program, Mr. Dove would certainly hire some large men who look like they can break bones, instead of these weird, gangly, dirty street musicians, but they wouldn’t be weird, only worrying, and this is going for weird.
This story is a little interesting from an archaeological standpoint, I think. There’s a thread about the old stories of old buildings, things that have always been around, photographed throughout time, that resurfaces in a later P.J. Hammond script for Sapphire & Steel. And now that I think about it, Michael Standing’s character, Mr. Spoon, is a spiritual antecedent of Johnny Jack in the final S & S story as well.
