"I just don't understand!" yelled a frustrated Sherlock Holmes, studying the old angel statue with his pocket magnifying glass. "There's not a single way that they could have disappeared! No windows, no secret corridors, no anything!"
John Watson sighed. The pair had encountered (and solved) may locked-room mysteries, but none as simple, yet complex, as this one. A rather older couple bearing the surname Williams had disappeared three days beforehand. They were last seen going to their cellar, which was locked from the inside. Nothing was found in the room except an angel statue, now covered in dust.
"Use your mind palace to figure it out!" John replied, irritated. "There's got to be something in there to help you."
Sherlock paused, pursing his lips, his hands together resting below his chin.
"We're going to a video store," he muttered.
John and Sherlock caught a cab. "Sparrow and Nightingale," Sherlock told the cab driver.
"Right then," the cab driver said, and sped toward downtown London.
"Why are we going to a video store?" John asked.
"I've heard of a similar case there."
The cab came to a stop, and after paying, the detective and his blogger entered Sparrow and Nightingale video store.
A blonde woman holding a baby was at the register, hushing it from its wailing. "Hello," she whispered. "Go ahead and take a good look around. Sorry about little Kathy."
"Are you Sally Sparrow?" Sherlock inquired.
She looked up from her baby. "Yeah... why?"
"I'm Sherlock Holmes, a detective, and I'm dealing with a case involving a stone angel."
Sally Sparrow stared at Sherlock.
"Let me show you the back room."
