A fellow-student of Kimo's niece is found dead at the bottom of a cliff. Although she had a reputation as a mean girl, she hadn't been at the college long enough for anybody to have had a strong enough motive to kill her and yet somebody knocked her out and pushed her over the cliff.

Although it's supposed to be the latest book in the series rather than the last one, the epilogue does feel like a farewell round-up.

A mother goes hiking with her 14 y.o. neurodivergent son. Two days later her body is found in a canyon, but did she fall or was she pushed and where is the boy?

Nice and twisty. Although it was obvious who the murderer wasn't going to be, it was fun finding out who it actually was.

A Washington politician asks Kimo to look into the cold case of the 1960s death of her father, who was on leave from Vietnam in Hawaii. Despite otherwise meticulous record-keeping by the Army, details of this case seem to have been lost.

Despite all the cautions in the book about leaping to the obvious conclusion rather than considering other possibilities, the obvious conclusion was pretty much correct even if the who remained elusive till the end.

Kimo's mother asks him to look into the case of a son of a friend of hers who has been charged with killing a cop while trying to break up a bar-room brawl

A bit predictable in places, but still a good, quick, easy read.
