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 hôtel.'
'You think, then, that you are not yet rid of all your conspirators?'
'I think that Jules might still have an accomplice within the building.'
'And that a bottle of wine could be opened and recorked without leaving any trace of the operation?' Babylon was a trifle sarcastic.
'I don't see the necessity of opening the bottle in order to poison the wine,' said Racksole. 'I have never tried to poison anybody by means of a bottle of wine, and I don't lay claim to any natural talent as a poisoner, but I think I could devise several ways of managing the trick. Of course, I admit I may be entirely mistaken as to Jules' intentions.'
'Ah!' said Felix Babylon. 'The wine cellars beneath us are one of the wonders of London. I hope you are aware, Mr Racksole, that when you bought the Grand Babylon you bought what is probably the finest stock of wines in England, if not in Europe. In the valuation I reckoned them at sixty thousand pounds. And I may say that I always took care that the cellars were properly guarded. Even Jules would experience a serious difficulty in breaking into the cellars without the connivance of the
