Maybe that's because the bottom cage of 23 is actually 4 cells and extends to r9,c4! Otherwise it would have been impossible as you say and would have involved a duplication in c2 which is not allowed.

Discovered the rogue #91 on the bus yesterday & groaned aloud -- not surprised to see it's already been the source of some discussion here. Anyway, so a duplicate-number Killer puzzle has now been spotted in the wild!
Incidentally is it just me, or are the two final puzzles in the book (supposedly requiring 60 & 90 minutes each) inexplicably easy? I found many of the preceding puzzles much much harder, whereas the penultimate one in particular is pretty straightforward, assuming you use the 45-sum rule to get started.
