‘I don’t have to account to you for anything.’ Hanna looked at me with dislike. ‘And I don’t see that this has anything to do with the assault on Ogilvie.’

‘Then you must be bloody blind,’ I said. ‘Or are you deliberately not seeing? The man who might have been your next Prime Minister is found dead in mysterious circumstances, another man investigating his death is assaulted, and you don’t see any connection! How did you get to become superintendent?’

Hanna took a deep breath and then relaxed. ‘You can’t insult me, Mr Kemp. You say you saw Ogilvie at the Blue Water Casino last night. What was he doing there?’

‘He was there to see me.’ I hesitated. I didn’t want to bring Jill Salton into this but Hanna was sure to find out she was there and he would wonder why I hadn’t mentioned it. Thus is suspicion born where none should exist. ‘I was there with Mrs Salton. We had driven over from El Cerco.’

‘What were you doing – gambling?’

‘No. We had a few drinks in the bar.’

Hanna was politely incredulous. ‘You drove all the way across Campanilla just to have a few drinks in the bar of the Blue Water Casino?’

‘Not at all. I went to see Ogilvie.’ Again I hesitated, but I decided that Mr Black was very well equipped to look after himself. ‘And to see Mr Negrini.’

‘Negrini? What about?’

‘About the manner of Salton’s death.’

‘Would he know about that?’

‘He might.’

‘Yes, he might,’ agreed Hanna. ‘But did he?’ He looked with disgust at the stub of his cheroot and extinguished it in the ashtray. ‘You needn’t answer that. He wouldn’t tell you if he did. But I find it interesting that you should think it necessary to ask him. Did Ogilvie talk to Negrini?’

‘A few words on introduction, that’s all. This isn’t getting us far, is it, Superintendent?’

‘I’m doing all right,’ he said placidly. ‘Who did you see yesterday, Mr Kemp?’

‘Am I being investigated?’

He smiled wickedly and leaned forward. ‘You should never antagonise a policeman, Mr Kemp. Failure to answer reasonable questions can be construed as obstructing the police in their duties. For a foreigner, this can lead to summary expulsion from Campanilla. You wouldn’t want that, would you?’

‘No,’ I said resignedly. He was right and I shouldn’t have pushed him so hard. A copper has too many ways of hitting back – and they’re all legal. ‘I saw Don Jackson at the Chronicle, Mrs Salton, her lawyer Mr Stern, a few house servants and the pilot and engineer of Salton’s plane.’ I paused, remembering. ‘And the pilot’s wife.’ I paused again and came up with one more name. ‘And Jake McKittrick.’

That brought a reaction. ‘Jake McKittrick! Why did you talk to him?’
