'You said that Hålén made his first payment?'

The man opened his briefcase where he kept the books and showed Wallander a receipt. It was dated the Friday from the week before.

Wallander thought it over.

'How long was he supposed to make payments for this encyclopedia?'

'For two years. Until all twenty instalments were paid for.'

This makes no sense, Wallander thought, no sense at all. A man who was planning to commit suicide doesn't agree to sign a two-year contract.

'What was your impression of Hålén?' Wallander asked.

'I don't think I know what you mean.'

'How was he? Calm? Happy? Did he appear worried?'

'He didn't say very much. But he was genuinely interested in the encyclopedia. I am sure of that much.'

Wallander did not have anything else to ask. There was a pencil on the kitchen windowsill. He searched for a piece of paper in his pocket. The only thing he found was his grocery list. He turned it over and asked Holmberg to write down his number.

'We will most likely not be in touch again,' he said. 'But I'd like to have your telephone number as a precaution.'

'Hålén seemed perfectly healthy,' Holmberg said. 'What is it really that has happened? And what will now happen with the contract?'

'Unless he has relatives that can take it over, I don't think you'll get paid. I can assure you that he is dead.'

'But you can't tell me what has happened?'

'I'm afraid not.'

'It sounds sinister to me.'

Wallander stood up to indicate that their talk was over. Holmberg stood rooted to the spot with his briefcase.

'Would I be able to interest you, Detective Inspector, in an encyclopedia?'

'Detective Sergeant,' Wallander said, 'and I don't need an encyclopedia right now. At least not at the moment.'
