The chemist arose and placed the phone book to one side. He beckoned to his visitor and led the way through the laboratory. Murdock was speaking as they walked along.
"I was just about to telephone the police," he explained. "Your arrival was a timely one. I needed advice, immediately, and I could think of no one who could help me."
"My advice on what?" questioned Savette, as they reached the far door. "Why should you need the police?"
"Here is the reason," declared Murdock, calmly.
He opened the door to the landing and pointed to the body on the floor. Doctor Savette drew back with an exclamation of surprise. Then he stepped forward and examined the body.
"The man is dead," he declared. "He appears to have been strangled." He stared silently at the still face; then looked up at Murdock. He stepped back and surveyed the body; then gazed at his living companion.
"Amazing!" he exclaimed. "Amazing, Murdock! The man bears a remarkable resemblance to you!"
"That is what puzzles me," declared the chemist.
"When did this box come here?" questioned Savette.
"Today," said Murdock. "Delivered by mistake. That, at least, is what Stevens told me. The truckmen are supposed to come for it at any time."
