They were now sitting together, drinking tea in the inspector's office. A short while later, a constable came with an envelope. He saluted the Inspector and placed an envelope on his table. The Inspector opened the envelope, took out the paper, and began reading it. Suddenly, he jumped as if stung by a scorpion. He handed the paper to Shahryar and held his head in his hands. Shahryar took the paper and looked at it. A spark appeared in his eyes. It was the post-mortem report. According to it, the cardiac arrest which caused the death was induced by a severe electrocution.
Shahryar did not jump like the Inspector. Instead, a faint smile spread across his lips. He handed the report back to Nasir. "This report has confirmed my theory," Shahryar said. "What do you mean?" the inspector asked, looking up in surprise. But Shahryar, instead of replying, sank deep into thought. "But how could he have gotten an electric shock? We didn't find any frayed wire or any other such thing in the entire room that could cause such a shock. The door was locked from the inside, so it was impossible for anyone to come from outside… Then how…?" the inspector left his sentence unfinished. He felt as if Shahryar was not even present before him, and talking to him was pointless. He leaned back in his chair. He knew that Shahryar would only emerge from his trance after reaching a conclusion.
After a long time, Shahryar suddenly awoke as if from a deep sleep. He said, "I have a suspicion. If it is proved to be true, perhaps such a strange method of murder has never been used before in the history of crime." "What do you mean?" the Inspector asked in surprise. "It means that this time, your culprit is a very intelligent scientist," he replied. "Sharry, why are you talking in riddles? Be straightforward," the Inspector said impatiently. "Be patient, my dear. First, tell me, did your staff bring the professor's walking stick?" "Why? Yes," the Inspector replied. "Quickly, get it and a small surgeon's forceps as well," Shahryar said, enjoying the Inspector's state. "Alright, I won't ask anything until you reveal it yourself," the Inspector said, exasperated. Then he rang the bell, and a constable immediately entered. The Inspector asked him to bring both items. After the constable left, they stared at each other, with Shahryar's expression mischievous, while the Inspector's was one of devouring.
In a short while, the constable entered with both items. Shahryar took the stick from him. First, he weighed the cane firmly in one hand, then held the handle with the other hand and began twisting it. The handle unscrewed, and he saw that the inside was hollow. He lifted it towards the light and peered inside. He then picked up the forceps, inserted them, and pulled them out with a jerk, and a coiled copper wire came out with them. It was in the shape of an antenna. He put the cane on the table. "Now listen…" Shahryar began, but then interrupted himself. "First tell me, have you stationed a guard at the professor's residence?" "No, what was the need for a guard there now? Besides, the professor kept all his important papers in his office," he replied. Hearing this, Shahryar stood up agitatedly. "Oh man, you're a complete fool. Let's go quickly, lest it be too late," Shahryar said. "What do you mean?" the Inspector asked, surprised. "Listen my friend, does your vocabulary have any words besides 'why' and 'what do you mean'?" Shahryar said exasperatedly. Then he gently explained: "I fear the killer might have removed the murder weapon from the crime scene." "But we sealed the room that very day," the Inspector said, getting up hastily. Instead of replying, Shahryar almost dragged him to the door. Both left the office in a state of panic, as if death were pursuing them. The other police personnel looked at them in surprise. But they, disregarding them, got into Nasir's jeep, and he drove it at full speed.
