Prompt: Mention all these words in a story that ends in a compromise: mechanic, spaghetti, bathtub, stool.
Lestrade bounded through the door of 221b Baker Street to find John and Sherlock seated at the table, glaring at each other over a large bowl of spaghetti.
"Er… sorry to interrupt," Lestrade put in, "but do you mind if I stay here for a bit? My car's at the mechanic down the street."
"It's fine," John responded, then went back to glaring at Sherlock. Lestrade looked to Sherlock, to John, and back.
"Am I interrupting something? I can probably find a café or someplace nearby to wait at…"
"No; it's fine," Sherlock said, not taking his eyes off John. They seemed locked in a staring – or rather, glaring – contest.
"Doesn't look like it's fine," Lestrade mumbled, but both Sherlock and John heard him.
"It would be fine," Sherlock said heatedly, "if John would give me back my revolver!"
"It would be fine," said John, in exactly the same tone, "if Sherlock would actually eat something for a change!" John looked to Lestrade for support in his argument, and then realized Lestrade had nowhere to sit. "Oh! Lestrade, there's a stool you can bring in from the hallway."
Lestrade mumbled his thanks and went out into the hall. He passed the bathroom, then backtracked. He had seen something… He poked his head into the bathroom and saw Sherlock's revolver sitting in the bathtub. Lestrade snorted with laughter and went to retrieve the stool. He came back in the room and sat down at the table. Just then, Sherlock got up and began to leave the room.
"Where are you going?" John asked angrily.
"To get my revolver. It's in the bathtub. Honestly, John. You call that a hiding place?" John was too shocked to be angry.
"But you never left the room! How could you possibly know it was there?"
"When Lestrade came back in, he was smiling – laughing, really. Obviously, he'd seen it. The only room in the hall between here and that stool is the bathroom. If Lestrade had seen it just by walking by, it had to be in the bathtub, obviously."
Sherlock walked out of the room and came back in with his revolver, which he set on a table. He came back to the table looking smug.
"You still have to eat something, Sherlock." John glared. Sherlock raised an eyebrow. "If you don't, I'll…" John thought for minute. Then he pulled out his phone and grinned. "If you don't, I'll give Molly your number!"
"You wouldn't."
"I would! But if you eat something, I swear I won't."
Lestrade walked out of the door to the sound of forks clinking against plates as John and Sherlock enjoyed their spaghetti.
