“The guest bedroom upstairs. I did a quick search inside. There were no clothes in the closet or in the dresser. The bathroom was spotless—no toothpaste mucking up the counter or sink. It was also decorated with guest towels, not regular towels.”

Marge was puzzled. “Guest towels generally go in the guest room.”

“That’s the point,” Decker said. “It is definitely a guest room.” He rolled his stiff, beefy shoulders. “There was no maid’s room downstairs, Margie. A house this big…think Mom cleans it by herself?”

Marge said, “So the maid isn’t a live-in. You want to know who she is.”

“It’s always good to take a look at the staff.”

Marge’s eyes lit up. “You’re thinking an inside job?”

“I’m just thinking out loud.”

Marge laughed. “So I’m leaping to conclusions. It relieves the boredom. I’ll go ask Sis to step inside now. You want to do the primary questioning?”

“You do it,” Decker said. “It’s officially your assignment.”

Marge paused, then shook her head.

“What?” Decker asked.

“There’s something spooky about this case.”

“Agreed,” Decker said. “We comb the house and everything looks in military order. There are clothes in the closet, food in the refrigerator, and three cars in the three-car garage. Everything’s perfect except where are the people? It’s as if the place had been nuked with a neutron bomb.” He paused. “Ready to talk to the sister?”

Marge nodded. They walked down the stairs into the marble entry. Suddenly Decker placed a hand on Marge’s shoulder, stopping her from opening the front door.

“Wait a second.” Decker crooked his finger, then pointed to the display cabinet. “What is wrong with this picture?”

Marge stared at the case. “What do you mean?”

“Something looks…out of place.”

Marge eyed the pieces up close, then took a step backward and studied the case. “The shelves are open. Aren’t most display cabinets enclosed?”

Decker said, “Now that you mention it, that’s a little weird, too. But that’s not what’s bothering me.”

Marge took another step forward and scanned the pieces one by one. The top glass shelf was host to two fighting dogs, the second one held a simple green bowl, the third had a set of metal parrots, and the bottom one gave support to two aquamarine vases with bas-relief dragons on them.

“Nothing looks broken.”

“Nope.”

“Strange dogs,” Marge commented. “All those colors dripping into one another. And the aggressive pose. Their backs are arched and they’re baring their teeth. They’re disconcerting.”

Decker nodded. It was the dog statues. Something about them was bugging him. He zeroed in on the teeth. Each statue had four pronounced canine teeth—two uppers and two lowers, all of them perfectly pointed. Not a chip or a crack to be seen.
