"Who was it, then?"
"Come, try and guess that yourself. It wasn't Goujon; I don't mind letting you know that. But it was a person quite within your knowledge of the case. You've mentioned the person's name more than once."
Nettings stared blankly. "I don't understand you in the least," he said. "But, of course, you mean that this mysterious person you speak of as having moved the body committed the murder?"
"No, I don't. Nobody could have been more innocent of that."
"Well," Nettings concluded with resignation, "I'm afraid one of us is rather thick-headed. What will you do?"
"Interview the person who took away the body," Hewitt replied, with a smile.
"But, man alive, why? Why bother about the person if it isn't the criminal?"
"Never mind—never mind; probably the person will be a most valuable witness."
"Do you mean you think this person—whoever it is—saw the crime?"
"I think it very probable indeed."
