A Grave Mistake

I was used to odd sounds coming from graves as I dug them and then filled them. But a ringing phone, despite being a sound I recognised, was still something I hadn't expected.

I was paid good money to not know anything about what I was doing. But I knew if this kept ringing, that could cause problems.

So I opened the sack, and found the phone. I should have just smashed it, but instead I answered it. An unfamilar voice answered it.

"You've made a grave mistake."

"You're a bit late."

"You've not buried him yet, yeah?"

I ran.
