“Are you not certain that it was a woman speaking?”
“To the best of my belief it was.” Mitchell paused. “I am sure it was a woman’s voice.”
“Have you tried to trace the call?”
“Yes,” somewhat glumly. “But Central had no record of it.”
“Then it did not come over a public telephone?”
“No, Sir.”
“Was it on a limited service wire?”
“No. Central declares not,” responded Mitchell. “She insists that it must have been sent by some one using unlimited service.”
Penfield paused to jot down a note on his memorandum pad before again questioning the inspector.
