Fifteen years ago, a teenage girl fell into a canal late at night. Unable to swim, she went under and started to drown, only surviving thanks to a nearby man, an alcoholic, who heard her splashes and pulled her out, though not before she suffered irreparable brain damage that left her in a state of permanent childhood, unable to learn or mature. The drunk man claimed he saw her thrown into the canal by another man, but the following day he couldn't remember a thing. Now, at a fundraising dinner for a Venetian charity, a wealthy and aristocratic patroness - the girl's grandmother - asks Brunetti if he will investigate. Sequel to "Falling in love". Bestseller. 2016.
