You were a tourist visting London, taking pictures and making memories with a few friends. One night, you wers heading back to the hotel when you heard crying. You follow it to see a woman in a cloak, limp and leaning against the side of a buidling, a basket clutched in her fail hands. She was motionless, seeming lifeless, but there were small cries coming from the basket.
What do you do?
