Mr. Heels was a villa holder who happened to be Dr. Kemp's nearest neighbour. He was one of the few gentlemen of the area who brushed aside the story of the invisible man as mere trash. Unlike the rest of the people of the countryside, he continued to scroll in his garden and have his afternoon nap in the summer house built up in the garden itself. However, he was not as brave as he pretended to be. Hence on waking up from his twenty minute nap that afternoon, he was quite intrigued to see Kemp’s entire window panes smashed to pieces. Twenty minutes ago, before he went off to sleep in the summer house, he had seen everything intact. It was only after he saw the house maid and Dr. Kemp escaping from the dining room window that the Invisible Man's presence struck Mr. Heelas. The thought panicked him and he ran blindly to the safety of his house. He got all the doors and windows closed securely and when Kemp came running to his house to seek refuge, this selfish and cowardly man refused to let him in, lest he himself should become a victim of the Invisible Man's wrath
Thus, we find him to be a mean, self-centred, cowardly person, who slammed his doors in the horrified face of poor Kemp when he needed help.
