Henry Kuttner, Chameleon Man (1941)

How the devil had her husband managed to get out of sight so suddenly, leaving an utter stranger in place of himself? She didn't know. She stared balefully at Vanderhof, who shrank back, his eyes on the umbrella. Just then the giantess caught sight of the fat little man at the arcade's entrance. ”
