“Can’t annoy me,” said the Goon. “No one has yet.” He must have gone on thinking about this while Howard was leading the way down the side passage into Upper Park Street. It was getting dark by then. The Goon’s head seemed to get lost upward in the dusk. When Howard looked up, he could hardly see anything beyond the Goon’s wide leather shoulders. “Funny,” the Goon’s voice came down. “Never been really angry. Wonder what would happen if I was.”

“I shudder to think!” Fifi said, more faintly than ever. “Howard, would you like to hold my other hand?”

Howard was going to refuse indignantly. But it dawned on him in time that Fifi was scared stiff. So was he. When he took her hand in what was supposed to be a comforting grip, his hand was as cold and shaking as Fifi’s. Joined in a line, they turned right and walked the short distance to the Poly. It could have been a shorter distance still, but Fifi took one look at the empty spaces of the park, and another, shuddering, at the gathering dark in Zed Alley and took the longer way around by the road and in through the main gate of the Poly.

By the time they got there bright strip lights were on in most of the windows of the Poly, and the forecourt, where the diggers were at work excavating for the new building, was well lit, too. There were a lot of people about, students hurrying home and men working on the site. It should have felt safe. But the Goon still had hold of Awful’s hand, and none of them felt safe. Fifi cast longing looks at several people she knew, but she did not dare call out for help. Howard twitched at her hand, trying to tell her that they could give the Goon the slip inside the building. They could go up in the elevator, down the stairs, through the fire doors, up in the other elevators, and shake him off in the crowds. Then they could phone the police.

They went up the steps into the litter of paper cups in the foyer. Howard turned toward the elevators.

“Don’t be too clever,” the Goon said. “Know where you live.”

Howard turned around and looked up at him. The distant small face held the usual grin, but just for an instant, before Howard looked clearly, it did not look quite as daft as he had thought. In fact, he could have sworn the Goon looked almost clever. But when Howard looked properly, he realized that it was just a sort of slyness. That was bad enough. Howard changed direction and led them all up the stairs instead, to the room where Dad usually did his teaching.
