Kemp was obliged to provide shelter to Griffin as the latter was his old acquaintances. However, after reading newspapers, Kemp realized that his fellow student had gone astray. It was imperative to control this waylaid scientist before he could prove to be a menace. Thus Kemp sent a note to Colonel Adye, the chief of police and laid a trap for Griffin. Unaware of this plan, Griffin schemed to let loose a reign of terror with Kemp’s support. Kemp in turn tried to divert his attention by suggesting that happiness could not be attained by playing a game against the race. He added that Griffin should get his work published and share it with his countrymen. It was at this point that Griffin heard footsteps coming upstairs. But Kemp tried to brush aside the sound and Griffin grew suspicious. He insisted on clarifying his doubt by personally examining the source of footstep sounds. Kemp now had no choice but to stop Griffin. This confirmed Griffin’s doubts and he called Kemp a traitor. Kemp’s well planned trap had been exposed. Griffin immediately started disrobing himself to become invisible and avoid arrest. Kemp’s efforts to lock him inside were failed. As Kemp struggled to close the door with both hands, the invisible Griffin gripped his throat. Kemp had no choice but to leave door handle to defend himself. Griffin pushed Kemp into the corner of the landing overpowered him and flung the dressing gown on top of him. Colonel Adye saw all this with great amazement. Just then he was hit with a great force and hurled headlong. An invisible foot trod upon him. He then heard the front door being slammed. Before they could register what had happened. Griffin had escaped.
