The next morning there were a lot of tourists with cameras in the Tower. But Walter, Mary, William and Anne were glad to see the people. The more people that were in the fortress, the more chance they had  to escape. ''Let's get over to the tower. That's Where most of the people go first,'' said Walter. So the four ravens went to the tower. A large group of tourists came by. The people put their bags down because there was a long line. They didn't want to hold Anne saw the tag she wanted to jump into . She saw tried to get in but she couldn't manage it . Anne landed near the woman's  leg and scracthed  her with her beak . Help l've been bitten by a raven . Help !   the woman cried . Two Beefeaters ran to the woman . Anne ran away quickly . The Beefeaters helped the woman  who now had a small scratch . Walter peaked out of his bag and saw Anne running away. He jamped out and run after her . William saw Walter and Anne running away . He didn't want to escape without them . At that moment  a tourist saw William inside his bag . He cried  There's a raven in my bag . Get out ! Get out! William jamped out and run as fast as he could . All the tourists grabbed their bags .A woman saw Mary under a flag and began to cry A raven! Help ! A raven ! Mary jamped out of the bag and ran away . The four ravens hid behind the wall for the rest of the day . So much for plan number one Walter said their heavy bags that were full of souvenirs.''Aha! Bags! Plan number one. Okay one. Okay everybody, find a bag and get into it,'' Walter told the ravens. Walter, Mary, William and Anne Walked Along the ground near the tourists' feet. William jumped into a bag. Mary got into another bag. But  it was full. She moved sweets, souvenir plates and flags around and finally got to the bottom of the bag. She stayed very still. Walter found an open bag. There wasn't very much inside it. He laid down very quietly.
