“With her growing reputation as a crime-solving expert and her deep knowledge of antiques, Jean teams up with Police Chief Inspector André Caron to unravel a series of mysteries.
“As more cases emerge and an old friend reappears, will Jean and Dom be able to keep their relationship intact amid the chaos?”
Speaking to the Radio Times on the opening of the fourth series, Lindsay said: “We open with two 75-year-old hotties on jet skis flying across the Mediterranean, and then they find a dead body. So, I don’t think I’ve seen that on television before. I hope I haven’t!
“And my husband’s done an amazing Hawaii Five-0 riff to it. So, that’s what I want everyone to start off with. But, actually, the edit’s come out really well. We’ve got some brilliant actors, brilliant friends in it again, so yeah, I’m very proud.”
