Lucy gets the same bus every day. Today, her journey home will change her life.Lucy can barely afford her weekly ticket for the grimy number 24, tries to avoid eye contact, and, if she’s really lucky, she gets a seat and reads a chapter of her book. But it’s a Friday – and the bus is always crammed at the end of the week. She keeps her elbows close and clings to a pole at every juddering stop. All she wants to do is get home to her dog, Billy, the only comfort she has right now.When she gets off, something feels different.An envelope stuffed with thousands of pounds is in her bag.Is it the answer to her prayers, or the beginning of a nightmare?Because, in the end, everything has a price.
