‘Why not? If Reginald Dimmock fell on mere suspicion that he would turn out unfaithful to the conspiracy, why not Prince Eugen?’
‘But it would be an unspeakable crime, and do infinite harm to the hotel!’
‘True!’ Racksole admitted, smiling. Little Felix Babylon seemed to brace himself for the grasping of his monstrous idea.
‘How could it possibly be done?’ he asked at length.
‘Dimmock was poisoned.’
‘Yes, but you had Rocco here then, and Rocco was in the plot. It is conceivable that Rocco could have managed it—barely conceivable. But without Rocco I cannot think it possible. I cannot even think that Jules would attempt it. You see, in a place like the Grand Babylon, as probably I needn’t point out to you, food has to pass through so many hands that to poison one person without killing perhaps fifty would be a most delicate operation. Moreover, Prince Eugen, unless he has changed his habits, is always served by his own attendant, old Hans, and therefore any attempt to tamper with a cooked dish immediately before serving would be hazardous in the extreme.’
‘Granted,’ said Racksole. ‘The wine, however, might be more easily got at.
Had you thought of that?’
‘I had not,’ Babylon admitted. ‘You are an ingenious theorist, but I happen to know that Prince Eugen always has his wine opened in his own presence. No doubt it would be opened by Hans. Therefore the wine theory is not tenable, my friend.’
‘I do not see why,’ said Racksole. ‘I know nothing of wine as an expert, and I very seldom drink it, but it seems to me that a bottle of wine might be tampered with while it was still in the cellar, especially if there was an accomplice in the hotel.’
