Sable heard it at eight-fourteen precisely.
She was in the armchair — the good one, with the flattened arm she'd worked on for months — and her eyes were almost shut. Almost. Then: *whump*. A low, heavy sound from somewhere in the dark living room. Sable's left ear rotated slowly toward it, like a small satellite dish finding its signal.
New sound. Unexplained. Unacceptable.
She dropped from the armchair without a noise — four paws, perfectly placed — and moved into the hallway. *Ears forward. Whiskers forward.* That was how you began an investigation. Sable had conducted many investigations. She knew the procedure.
The living room smelled of dust and something faintly electric, like the air before a storm. Sable stopped in the doorway and took it in, nostrils working. Dust. Electricity. And something else — something small and cold, like metal on a wooden floor.
She looked at the blue couch. One cushion had been knocked completely sideways and was leaning against the leg of the coffee table at a very suspicious angle. Sable circled it twice. No creature underneath. No creature behind. Just the cushion, lopsided and guilty-looking.
*Ears forward. Whiskers forward.* She moved on.
The green rug in the middle of the room had a lump in it. A round, trembling, unmistakably *breathing* lump. Sable approached at an angle, the way you approach something you're not sure about. Two enormous eyes blinked up through the fringe of the rug. Then a small white nose appeared.
"It woke up," whispered Pip, the kitten from upstairs. "The big grey monster. It woke up on its own and I heard it and I hid and it's going to eat us."
Sable looked at Pip. She looked at the vacuum cleaner in the corner. She looked back at Pip.
The vacuum cleaner stood exactly where the humans always left it — grey and humped and still, its long hose coiled on top like a sleeping snake. Sable had watched the humans take it from the cupboard. She had watched them wrestle it around the furniture and put it back. She had watched it many, many times. It had never eaten anything she hadn't already inspected first.
*Ears forward. Whiskers forward.* She crossed the room and pressed her nose to the vacuum's plastic flank. It smelled of dust and old carpet and absolutely nothing dangerous. She walked the full circle of it, slow and deliberate, checking every side.
Then — *tink* — something small rolled out of the vent at the bottom and skittered across the floorboards.
Sable stopped it with one precise paw.
A marble. Blue glass, with a white swirl inside. She looked at it. She looked at the vacuum. She looked at Pip, who had emerged from the rug and was now sitting very upright, pretending to have been perfectly calm the entire time.
Pip's marble. In the vacuum's vent. Which meant Pip had lost the marble near the vent. Which meant the marble had rolled in. Which meant the *whump* was just the marble — just a small glass ball — bumbling through the machine and landing at the bottom.
Sable carried the marble back in her mouth and set it down in front of Pip with a small, definitive click.
She gave Pip one slow blink. Pip's ears went flat, then slowly came back up.
Then Sable turned, walked back to the hallway, jumped up to the good armchair — the one with the flattened arm — and tucked her front paws neatly underneath her chest.
*Ears forward. Whiskers forward.* Then slowly, slowly, both going still.
Below, on the green rug, Pip curled into a small white circle, chin resting on the returned marble, eyes finally closed.
