"I am convinced that, whoever she may suspect, she knows nothing of the murder," he said shortly.
"Then she does suspect somebody?"
Tarling nodded.
"Who?"
Again Tarling hesitated.
"I think she suspects Milburgh," he said.
He put his hand in the inside of his jacket and took out a pocket case, opened it, and drew forth the two cards bearing the finger impressions he had taken of Odette Rider. It required more than an ordinary effort of will to do this, though he would have found it difficult to explain just what tricks his emotions were playing.
"Here are the impressions you wanted," he said. "Will you take them?"
Whiteside took the cards with a nod and examined the inky smudges, and all the time Tarling's heart stood still, for Inspector Whiteside was the recognised authority of the Police Intelligence Department on finger prints and their characteristics.
The survey was a long one.
