Query: Chaos in the black hole S-matrix   Recent work by Shenker, Stanford, and Kitaev has related the black hole
horizon geometry to chaotic behavior. We extend this from eternal black holes
to black holes that form and then evaporate. This leads to an identity for the
change in the black hole S-matrix (over times shorter than the scrambling time)
due an addition infalling particle, elaborating an idea of 't Hooft.
