"35. 1) up2) back 3) out4) in   Sergeant Frank Spike sat behind his desk and stared out of the window. Outside, a steady stream of traffic passed 30_______, each car moving slowly in the cold, grey rain. Just as Frank was sighing heavily, Inspector Spencer 31_______ up near his desk, with his perfect white teeth and enthusiastic smile. It was true he had neither the looks nor charm of Spencer – sorry, Inspector Spencer – but the younger man didn't have Frank's 'nose for crime'. That nose meant Frank could get inside the mind of the criminal and figure 32_______ the trickiest of cases. As a result, the younger man often asked for Frank's help.  'Hey, Frank, do you mind if I ask for your advice on something? Have you heard of the Babbingtons?'  Everyone had heard of the Babbingtons. Ronald Babbington was the millionaire owner of Babbington Oil, and his wife Tabitha was a model. Together they enjoyed nothing more than 33_______ off how rich they were. Most recently, they had invited the press to take photographs of the enormous diamond Ronald had bought for his bride.   'We've had some secret information about a plan to steal the Babbington diamond! What do you think is the best thing to do?'  Frank 34_______ thoughtfully out of the window. The sound of a car horn brought him 35_______ to the case. He 36_______  his fingers together under his chin to look as if he was thinking deeply. 'Listen, do this the clever way,' said Frank, leaning towards the younger officer. 'What you need to do is let them commit the crime. If you catch them red-handed, you've got all the evidence you need, no problem.'"
