I have been thinking what I should tackle next; and I am inclined to believe that there is a good deal to be done in the way of so-called undecipherable inscriptions.'
'Your line of study pleases me,' said Dyson. 'I think it may prove useful' But in the meantime, there was surely something extremely mysterious about the case of Sir Thomas Vivian.'
'Hardly, I think. I allowed myself to be frightened that night; but there can be no doubt that the facts are patient of a comparatively commonplace explanation.'
'Really! What is your theory then?'
'Well, I imagine that Vivian must have been mixed up at some period of his life in an adventure of a not very creditable description, and that he was murdered out of revenge by some Italian whom he had wronged.'
'Why Italian?'
'Because of the hand, the sign of the mano in fica. That gesture is now only used by Italians. So you see that what appeared the most obscure feature in the case turns out to be illuminant.'
'Yes, quite so. And the flint knife?'
'That is very simple. The man found the thing in Italy, or possibly stole it from some museum. Follow the line of least resistance, my dear fellow, and you will see there is no need to bring up primitive man from his secular grave beneath the hills.'
