"How?"
"That—that is the problem before us. When we learn just exactly how she scratched herself, or was scratched—" Kennedy paced up and down in front of the fireplace. Then he confronted each of us in turn, suddenly serious. "Not a word of what I have discovered," he warned.

TANGLED MOTIVES
"Do you wish to examine the people now?" Mackay asked.
Kennedy hesitated. "First I want to make sure of the evidence concerning her actual death. Can you arrange to have the clothes she has on, and those she brought with her, all of them bundled up and sent in to my laboratory, together with samples of her body fluids as soon as the coroner can supply you?"
Mackay nodded. This pleased him. This seemed to be tangible action, promising tangible results.
Again Kennedy glanced about in thought. I knew that the scratch was worrying him. "Did she change her clothes out here?" he inquired.
The district attorney brightened. "She dressed in a small den just off the living room. I have a man posted and the door closed. Nothing has been disturbed."
He started to lead the way without further word from Kennedy, proud to have been able once more to demonstrate his foresight.
