In the bags?
From the spot behind the vegetable plants on the balcony it is impossible to see the secret hatch leading deep underground to the land of the ever watching Ant People! From where the balcony-dwellers spy on the neighbors and the strangely varying black trash bags there is no way to see that the real police (Ant People) are monitoring it all.
Not bodies.. no, only telltale items that would link the residents to their dinner and garden fertilizer. 🌹🌻🍅🥦
Over dinner those odd neighbors wonder why noone has noticed their green thumb when the ground in their area is just short of a hazmat site.. ☣️
