Bernard with Maxie and 99.
CONTROL Agent 42 who is stationed in a trash can in downtown New York, the only area in the state from which all the trash cans have not disappeared.
Bernard reports "nothing suspicious so far, but the city-refuse have tried to collect me three times," leading Smart to deduce that "someone at County Hall is collecting the garbage but not returning the trash cans."
