‘Not a very dear friend, Miss Marcia. I first made his acquaintance, I believe, on the day that you discovered Marcellus.’

‘How did that happen?’ Mrs. Copley asked.

‘I heard him talking in a café.’

‘It’s a pity you didn’t hand him over,’ said Melville. ‘You would have saved the police considerable trouble. It seems they have been watching him for some time.’

‘I wasn’t handing people over just then,’ Sybert returned dryly. ‘However, I don’t see that the police need complain. It strikes me that he has handed himself over in about as effectual a way as he possibly could; he won’t go about any more sticking stilettos into kings. The Italians are an excitable lot when they once get aroused; they talk more than is wise—but when it comes to doing they usually back down. It seems, however, that this fellow had the courage of his convictions. After all, it was, in a way, rather fine of him, you know.’

‘A pretty poor way,’ Melville frowned.

‘Oh, certainly,’ Sybert acquiesced carelessly. ‘Umberto’s a gentleman. I don’t care to see him knifed.’

‘What I can’t understand,’ reiterated Melville, ‘is the fellow’s point of view. No matter how much he may object to kings, he must know that he can never rid the country of them through assassination; as soon as one king is out of the way, another stands in line to take his place. No possible good could come to the man through Humbert’s death, and he must have known that he had not one chance in a hundred of escaping himself—I confess his motive is beyond me. The only thing that explains it to my mind is that the fellow’s crazy, but the police seem to think he’s entirely sane.’

Sybert leaned back in his chair and studied the flowers in the centre of the table with a speculative frown.

‘No,’ he said slowly, ‘the man was not crazy. I understand his motive, though I don’t know that I can make it clear. It was probably in part mistaken patriotism—but not entirely that. I heard him state it very clearly, and it struck me at the time that it was doubtless, at bottom, the motive for most assassinations. His words, as I remember them, were something like this: “Who is the King? He is only a man. Why is he so different from me? Am I not a man, too? I am, and before I die the King shall know it.”’
