The One Who Got Away The Doctor paced up and down in Sir Charles’s library, while his host looked on anxiously. ‘Take my advice, Doctor. Try to relax. There’s no point in upsetting yourself like this.’ ‘He should have been back hours ago,’ said the Doctor. ‘I should never have let him go.’ ‘You know what young people are like.’ Sir Charles tried to ease matters. ‘He’s probably quite forgotten your instructions. He could be off doing something else.’ The Doctor shook his head. ‘Not that young man. He seemed far too responsible to me. No – if he hasn’t phoned back it’s because he isn’t able to. Something must have happened.’ ‘But what?’ The Doctor didn’t like to speculate. ‘But if you’re really concerned,’ went on Sir Charles, ‘perhaps we should contact the police.’ ‘Using the police at this stage might just drive this menace underground,’ said the Doctor. Sir Charles had heard all this before, as the Doctor had expressed his fears.
