In my (Bookwalker) version it’s a bit weird but they are using an unusual kanji for うそ…
Here they are displayed side by side in Jisho. The top one is the one my IME gives me, but my book contains the bottom one… Therefore I could not find this line in my book just by typing it in. (Just in case somebody else also has issues finding this spot: this is probably why!)
EDIT: I looked further into this and Kanjipedia is convinced that the bottom one is the one that should be used…
Somehow reminds me of what’s going on with 殺人出産 …
