Five White Fingers

According to Wireless Weekly:

“We can’t stop Ada laughing,” said Mrs. Plackett’s sister, Alice, and this was the final strange happening of the two crowded days that followed the coming of the Five White Fingers to the Plackett household. The wealthy widow found this curious relic in a small antique shop, and although her friend, Henry Merriott, swore it was genuine, her agent was frankly sceptical. The mischief worked by these restless fingers forms the basis for this comedy... but is it a comedy or has Ada’s laughter a macabre sound? Twist and countertwist are presented in this intriguing play that ranges from broad satire to sheer horror.^[8]
