When she spoke to Griggs again the tone of her voice had changed.
'Please tell me how it could have been done,' she said.
'Easily enough.

A steel bodkin six or seven inches long, or even a strong hat-pin.

It would be only a question of strength.' Margaret remembered Mr.Van Torp's coarse hands, and shuddered again.
'How awful!' she exclaimed.
'One would bleed to death internally before long,' Griggs said.
'Are you sure ?' 'Yes.

That is the reason why the three-cornered blade for duelling swords was introduced in France thirty years ago.

Before that, men often fought with ordinary foils filed to a point, and there were many deaths from internal hemorrhage.' 'What odd things you always know! That would be just like being run through with a bodkin, then ?' 'Very much the same.' 'But it would have been found out afterwards,' Margaret said, 'and the papers would have been full of it.' 'That does not follow,' Griggs answered.
