Escaping From The Quarry

I've got something new for you, boss. One of the new slaves, that Oscar guy — I think he's planning an escape from the quarry! I saw him slip a piece of marble into his shoe a few days back to smuggle it past your guards. I thought he just wanted to trade it in, you know, for some herbal tea or a clean shave. But I awoke last night to the sound of stone banging against metal shackles. He's trying to rid himself of your chains! That's all I can tell you. Surely, it's worth a reward, right? Please, will you let me go now? Haven't I done enough for you?
