But as they puff round a corner in peaceful Pollok Park, Lola glimpses something that shouldn't be there: a high-end BMW. Doors gaping. And a man and a woman, roped together.
The man is stiff, cold. There's a bullet wound above one open, staring eye. The woman is unconscious - but alive.
Lola's early morning run is now a crime scene.
The young woman is Fiona Balfour. She and the dead man were due to be married next month.
Fiona says she can't remember what happened. But Lola's not sure she believes her.
Then Lola uncovers strange similarities with a case in Liverpool from five years before. Her victim may be alive, but she's in very real danger.
Lola's now in a race against time to stop the killer before they return to finish what they started.
Fans of Matt Brolly, Nadine Matheson, Alex Gray, Ian Rankin, Caro Ramsay and Denise Mina will devour this page-turning crime thriller.
