The Only One Left by Riley Sager

2.0

The final plot twist makes absolutely no sense and frankly, ruins the book.
Are we supposed to believe that Kit, a caretaker who is extremely familiar with bedridden/wheelchair-bound elderly patients, doesn't notice that Lenora/Virginia doesn't have atrophied muscles when she massages them for two hours every day? Anyone who has ever had to go through physical therapy will know how completely bogus this is. Kit also tested her reflexes, that's not something that you can fake. You can't just "will" yourself to not move.
