“Did she muffle the bell or did the killer?” he said.
Raising his voice, Adams called Fletcher.
“Did you check the telephone bell for prints?” he asked, as Fletcher came to the door.
“Yeah. It’s clean.”
“Didn’t you see the bell was muffled ?”
“Sure, but I didn’t think anything of it.”
“You wouldn’t,” Adams said in disgust. “No prints at all?”
Fletcher shook his head.
“Looks like the killer did it,” Donovan said. “She would have left a print.” Adams waved Fletcher away.
“Better find out if anyone heard the bell ring during the evening.”
