Olga Marie Cabral, Unhallowed Holiday (1941)
“ There was more to it—an indefinite, but horrifying more—the one bit that Julia had held back from Cliff. The day before she had seen the invisible playmate! In bright sunlight, grass rippling gently as though some small animal stirred at its roots; a small, furtive round, like the passage of a snake... She, Julia, had crossed the lawn to call Gin for lunch. The child was sitting quietly under a big beach unbrella, making a crude, crayon sketch. Julia, smiling and looking down over Gin's shoulder, saw the scrawled likeness of a little boy in blue overalls. ”
