Don’t Ever Get Old reminded me a lot of The 100-Year-Old Man Who Climbed Out the Window and Disappeared, both because of the age and cynical view of its hero and also because of the many murders that accompany the narrative. This book is a straight mystery, in which the hero and crime solver is a retired detective hunting for the guard who beat him up in a prisoners’ camp during WWII, and his sidekick is his impetuous grandson. The mortality rate is high, the action sustained. I particularly liked the notes that the hero keeps for himself as a device to stave off dementia and the sympathetic and never condescending portraits of the old hero and his wife. On the other hand, the plot is only barely believable, if lively. Fun if you don’t think about it too much!
