You could try the book Chess: 5334 Problems, Combinations, and Games by Laszlo Polgar. There are over 300 Mate-in-One puzzles that get progressively more difficult, and then the book continues with Mate in Two (over 3,000 puzzles), Mate in Three, and then combination puzzles. The book is a bit older so some libraries have a copy of it, or you can get a relatively cheap copy online.
Mate in 1 puzzles!!
Mate in one, with a twist of course, so you are warned!
Solution (in white text, highlight to see):
A little inspection reveals there are really 9 black pawns on the board as Be4 must be a promoted pawn. In order to make the position legal, one of those 9 pawns must be removed. Whichever you choose, in the remaining position there is always a mate in one! Except for pawn g4. However, after removing g4 the position is still illegal and no mate needs to be supplied! Feel tricked? You were!

Cool! Very smart--I appluad.
Mate in one

1.Ndb4# The other move which seemingly mates is 1.0-0-0 but it is illegal since the black rook on a2 could never have arrived there without moving Ra1!

Why must the Be4 be a promoted pawn and not a normal bishop?
OOPS!! Bh8 is supposed to be Black! Sorry!
1 little buggy removed, 1 little buggy added. Only 1 mate remains, but now there are 2 dark-squared black bishops on a7 and h8!

How could the normal bishop have left its home square c8 in this pawn formation?
Most mate in one puzzles are boring and easy. Can you post a hard one?
