Mr Blood shouted again and again. Nobody came to let them in. Up in the sky, a pale moon shone down on the hall’s black towers. “Are you sure this is the right place?” Edgar asked. “This is the right place,” Mr Blood replied. He pointed up at two large stone crows that stood on top of the gateposts. “The letter told us to come to Crow Hall.” “Who sent the letter?” asked Edgar. “At the bottom of the letter are the initials, ‘C. H.’” Mr Blood said. “The letter said the house was haunted,” said Mary. “Maybe C. H. is in trouble inside the house.” “We will have to climb over the gates and bang on the door,” said Mr Blood. Mr Blood began climbing up the black iron gates. Mary went after him. Edgar looked up at the sharp metal spikes on top of the gates. “Are you sure this is a good idea?” he asked. “Come on!” Mr Blood called from the other side of the gates. They walked up the path to the main door. There were two more crows carved into the black wood of the door.
