So its starts with a woman getting her handbag snatched, and the ensuing chase to retrieve it by a few good samaritans. However all that went through my head was why was she there at quarter to mid night with a baby? She wasn't getting on the train, or saying bye to someone( if she was they would have been off the train to check on her and the baby( even she didn't check her baby. Then didn't give her details to the police on the pretext baby needed a feed and walked off into the night. Totally suspect as cane to light later. So unbelievable . So why am I hooked? Hoping the plot improves
