Yasmin Marley as WPC Heather McIntyre in Wavelength
Heather McIntyre was a Women Police Constable who served at Maryhill CID and was a possible love interest for DCI Michael Jardine. It is unknown if they ever actually got together, although various episodes show that there appeared to be some mutual attraction between them. In Football Crazy, he considered ordering some flowers for Heather but didn't want it to be seen as sexual harrassment in the workplace. Unfortunately for him, Robbie overheard and actually sent some to her but as though Michael had. Heather also attended Jackie and Brian's wedding in Falling in Love and that is the last we see of her.
