10. The Lock

It took Sanders two hours to arrive at the point of interest. He knew the place well. It was an old, abandoned hut in the forest, which he and Teddy used to visit years ago. When Sanders approached the hut, a peculiar object caught his eye. There was a strangely shaped, wooden piece on the ground, with all of its sides painted in various colors. Sanders briefly examined the object, then promptly moved to the hut.

The door was closed and secured by a metal lock. Sanders tried to break them, but the lock and the door were very sturdy, so he quickly gave up.  The detective calmed down and decided to carefully examine them. The door was solid wood and the lock was kept closed via a secret, 4-digit combination. If Sanders wanted to get inside the hut, he had to crack it first.
