Skeleton

I and my friend were standing near the bank of the river. just then my friend said - look.

what?

there.

I saw an arm of skeleton - rather I should say arm bone - radius and ulna and along with bones of hands.

he started moving towards it. I tried to stop him.

what do you think - is it murder victim?

but before i could say anything , I heard scream of my friend.

skeleton hand has grabbed him from leg and was dragging inside the water. Soon my friend was under water and out of sight.
