The Misplaced Battleship by Harry Harrison - It might seem a little careless to lose track of something as big as a battleship ... but interstellar space is on a different scale of magnitude. But a misplaced battleship-in the wrong hands!-can be most dangerous.
When it comes to picking locks and cracking safes I admit to no master. The door to Inskipp's private quarters had an old-fashioned tumbler drum that was easier to pick than my teeth. I must have gone through that door without breaking step. Quiet as I was though, Inskipp still heard me. The light came on and there he was sitting up in bed pointing a .75 caliber recoilless at my sternum.
"You should have more brains than that, diGriz," he snarled. "Creeping into my room at night! You could have been shot."
"No I couldn't," I told him, as he stowed the cannon back under his pillow. "A man with a curiosity bump as big as yours will always talk first and shoot later. And besides-none of this pussyfooting around in the dark would be necessary if your screen was open and I could have got a call through."
Inskipp yawned and poured himself a glass of water from the dispenser unit above the bed. "Just because I head the Special Corps, doesn't mean that I am the Special Corps," he said moistly while he drained the glass. "I have to sleep sometime. My screen is open only for emergency calls, not for every agent who needs his hand held."
"Meaning I am in the hand-holding category?" I asked with as much sweetness as I could.
"Put yourself in any category you please," he grumbled as he slumped down in the bed. "And also put yourself out into the hall and see me tomorrow during working hours."
He was at my mercy, really. He wanted sleep so much. And he was going to be wide awake so very soon.
"Do you know what this is?" I asked him, poking a large glossy pic under his long broken nose. One eye opened slowly.
