No Mate in One Cluster

Black

White

Add a Black Queen, a White Rook, and a White Knight to create a No Mate in One Cluster for White (a legal position in which there is no mate in one for White, but if any Black piece except the King is removed, there is a mate in one for White).

EDIT: Obviously not the only solution, though.
