‘Yes; but of course I can’t say how much of each he ate. The plates were all soiled, and the dishes empty—that is to say, with the exception of the rice soufflé. There was a fair amount of that left.’

‘Ah!’ said Poirot, and seemed satisfied with the fact.

As we descended to the flat again he remarked in a low tone:

‘We have decidedly to do with a man of method.’

‘Do you mean the murderer, or Count Foscatini?’

‘The latter was undoubtedly an orderly gentleman. After imploring help and announcing his approaching demise, he carefully hung up the telephone receiver.’

I stared at Poirot. His words now and his recent inquiries gave me the glimmering of an idea.

‘You suspect poison?’ I breathed. ‘The blow on the head was a blind.’

Poirot merely smiled.

We re-entered the flat to find the local inspector of police had arrived with two constables. He was inclined to resent our appearance, but Poirot calmed him with the mention of our Scotland Yard friend, Inspector Japp, and we were accorded a grudging permission to remain. It was a lucky thing we were, for we had not been back five minutes before an agitated middle-aged man came rushing into the room with every appearance of grief and agitation.

This was Graves, valet-butler to the late Count Foscatini. The story he had to tell was a sensational one.

On the previous morning, two gentlemen had called to see his master. They were Italians, and the elder of the two, a man of about forty, gave his name as Signor Ascanio. The younger was a well-dressed lad of about twenty-four.

Count Foscatini was evidently prepared for their visit and immediately sent Graves out upon some trivial errand. Here the man paused and hesitated in his story. In the end, however, he admitted that, curious as to the purport of the interview, he had not obeyed immediately, but had lingered about endeavouring to hear something of what was going on.

The conversation was carried on in so low a tone that he was not as successful as he had hoped; but he gathered enough to make it clear that some kind of monetary proposition was being discussed, and that the basis of it was a threat. The discussion was anything but amicable. In the end, Count Foscatini raised his voice slightly, and the listener heard these words clearly:

‘I have no time to argue further now, gentlemen. If you will dine with me tomorrow night at eight o’clock, we will resume the discussion.’

Afraid of being discovered listening, Graves had then hurried out to do his master’s errand. This evening the two men had arrived punctually at eight. During dinner they had talked of indifferent matters—politics, the weather, and the theatrical world. When Graves had placed the port upon the table and brought in the coffee his master told him that he might have the evening off.
