FILE No.171Unsolved
The warehouse door was secured on the inside with a thick iron bar. There were no windows, and neither ceiling nor floor was broken. When the door was broken down and people went inside, valuable goods were gone. No one was inside.
The door's hinges are on the outside, and all three pins were wet with fresh oil. On the ground below the pins lay fine metal shavings.
How did the culprit get in and out of the warehouse?
If you get stuck, open the hints one at a time, in order.
Which side of the door is the bar on?
Which side of the door are the hinges on?
What was done to leave the oil on the pins and the shavings?
How did the culprit get in and out of the warehouse?
Choose the answer closest to the truth.
Pulled out the hinge pins, took the whole door off to get in and out, then put the pins back
The answer is "Pulled out the hinge pins, took the whole door off to get in and out, then put the pins back."
The hinges are on the outside, and the pins were wet with fresh oil. The culprit probably oiled them to pull and insert the stiff pins. The shavings beneath the pins are also traces of pulling and inserting the pins. The bar stayed in place on the inside, and if the whole door is taken off, one can get in and out.
A thick iron bar cannot be moved with a thread. The ceiling and floor were not broken, and no one was inside.
Because you think that with the bar in place, the door cannot be opened.
