This book had some serious problems, but ... I'm willing to listen to the sequel. Here's what you can expect if you're curious:
Widower Paul Jacobsen cannot remember anything from the previous five years once he feels asleep - nothing - zip, zero, zilch; he's had this condition for a while as our story opens at the retirement home in Hawaii where he's just moved in at the urging of his son. He finds some trash in his flat, goes to dump it in the trash chute, where he finds a corpse blocking his contribution.
Detective Saito begins by harassing Paul, scoffing snottily at his "condition". Until the murderer is caught at the end, Saito is about as obnoxious a cop as I've ever encountered, as well as stupid. Well, co-stupid with Paul (and his family) who apparently haven't had Paul's doctor confirm the condition. Incident after incident happens where circumstantial evidence keeps pointing at Paul, with Saito urging him to "confess" like an Inquisitor of a heretic at the stake, an example: Paul goes to buy stamps at the complex office, the receptionist on the phone asks him to bring the cash box over to her, he gets his prints on it, money is later stolen, so Saito goes nuts.
At one point in the book, Paul goes out for the day with his visiting family to a Sea World-like place. After a while they're "munching hamburgers" before they see more stuff there, and then they "have lunch" -- were the burgers a late breakfast? The end is fairly wild, almost James Bond-like.
Secondary characters include Meyer, a former D. A. and judge going blind from macular degeneration, and Henry, a math genius with Aspergers Syndrome, who are at at his table for meals. Meyer is a good guy, ever patient with Paul's memory lapses, stumbling on the "solution" of having Paul keep a daily journal with a MUST READ: IMPORTANT! note on top to see every morning. (Apparently, no one had thought of this before.) Henry is toad-like and nasty, tossing insults while hovering over his plate like Scrooge McDuck over a pot of gold, while tossing out insults.
Other faces include Marion, who becomes Paul's girlfriend/lover right away (the book takes place over a period of roughly a couple of weeks I think), as well as Paul's son, Denny, who visits a couple of times from the mainland. More than once he has to deal with "situations" caused by Paul's memory loss, and charge-ahead approach. Paul's 11 year old grand-daughter is also brought into the story; he's horrified that she's found out about his screwing Marion, but she's fine with it. Okay.
In addition to his blindness, Meyer suffers from incontinence ... which unfolded in a rather bizarre manner I thought. Not long into the story it's mentioned that issue isn't really a big deal exactly. But, as soon as we hear of it the problem seems to escalate exponentially, so that near the end, Meyer is having serious episodes regularly. In addition to the timing here, I had a major problem that there's never a mention of ... say ... seeing a doctor before deciding "that's just the way it is (or is gonna be)." Moreover, the book was written in 2007, yet when Paul asks if he listens to audiobooks, Meyer responds, "I can't. I tried, but I get the tapes all mixed up cuz I can't see well enough!" Did visually impaired clients still use cassettes then? Even so, tapes and CD's aren't that difficult to keep straight, and Meyer says elsewhere he can read some things with a magnifying glass - maybe including "Cassette 1"? Finally, as a former "D. A. and judge" he's there at times when Saito abuses Paul, yet never says a word, except one offhand comment (without Saito) that maybe Paul should think about a lawyer.
So, after all that, why would I be willing to give the series another chance? Well, the narration's pretty good, and despite his gruff (sometimes obnoxious) manner Paul is loyal and means well. Besides, according to the blurb of the next book, Paul leaves Hawaii, so no more Saito.
