For some time there was silence. Malcolm Sage appeared to be pondering over the additional facts he had just heard.
"What do you want me to do, Mr. Sage?" enquired the inspector at length.
"I was wondering whether you would run down with me this afternoon to Gorling."
"I'd be delighted," was the hearty response. "Somehow or other I feel it's not an ordinary murder. There's something behind it all."
"What makes you think that?" Malcolm Sage looked up sharply.
"Frankly, I can't say, Mr. Sage," he confessed a little shamefacedly, "it's just a feeling I have."
"The laboratory has been locked up?"
"Yes; and I've sealed the door. Nothing has been touched."
Malcolm Sage nodded his head approvingly and, for fully five minutes, continued to gaze down at his hands spread out on the table before him.
"Thank you, Carfon. Be here at half-past two."
