Quart-er past Dead

Mendez strides away from the amused looking Bodush, still clutching the recently aquired ‘Magical’ buckler.
“ 5,000gp! I’ll show that villainous merchant the meaning of stupid.”
Leaving the main parades of shops, Mendez enters the maze of small streets and alleys and finds his way back to ‘Quart's Wonderland’.
From what he’d previously noticed about the old man, Mendez can safely assume he’s a Wizard. But how powerful could he be?
Although appreciative of Bodush’s ability, Mendez maintains a deep mistrust of the arcane. This though is merely born out of a complete lack of understanding.
... Still, a Wizard’s just flesh and blood.
Finding a good hiding place, Mendez crouches down and waits until evening.
It’s surprisingly late when Quart finally leaves his shop. He seems to cast a few spells over the entrance and starts to shuffle off down the street.
Mendez checks that there'll be no witnesses and steps out of the shadows.
Without a word, Mendez notches three arrows simultaneously into his bow and lets them fly silently into the back of the old man.
Slightly surprised by the Wizards lack of magical protection, Mendez runs forward and drags the obviously dead body out of sight and quickly checks through his robes…
A dagger and a small purse… plus the shop keys!
Mendez licks his lips.
There were many expensive items in that shop, but he’s certain that they’ll be magically guarded.
Instead Mendez takes the cursed shield and pushes the edge into the dead merchants mouth until it slices through skin.
“Now we’re both smiling.”
With a final look over his shoulder, Mendez slinks through the darkness and back to his friends.
