This is one of those Midsomer Murders that is a little hard to follow because one's attention tends to wander.
It's a total eclipse of the sun, and Jeremy Harper and other astronomers watch it outside. Harper is found dead by head trauma from a meteorite.
The police in the form of Barnaby and Jones are brought in. Harper had fought with Laurence Janson, who headed the university observatory and planned to extend it onto Moonstone Ridge, the place where they watched the eclipse. Also, his wife Catrina is involved with Janson, though Harper doesn't know that.
The local astrologer, Mags Dorner, had told Jeremy that disaster was coming. She informs Barnaby that Moonstone Ridge has been cursed since Catrina Harper's sister Mary died there years earlier.
Then there are other murders. Meanwhile the newspaper is playing it up, and Mags, who works for the paper, is in her glory.
Mags runs around showing people their charts. Barnaby, however, is convinced that she's hiding something. He's determined to find out what it is.
Astrology can be fun but this episode made it kind of boring. Plus the episode seemed to mix astrology, astronomy, and psychics together. Barnaby and Jones are becoming more cohesive as a team, which is nice.
