Christmas puzzles - Day 2

After yesterday's challenging little puzzle, here's something to test your ability at retrograde analysis.   As it's Christmas Day, it is a Christmas tree of course.   It's Black to play and mate in 2.

It should be easy to work out that White has just played one of two moves... but which one?   Only one is correct!
