This was a really well-done story - it clearly kept me turning pages to finish it in a day. The voice of Del was a bit off at first - didn't sound like a man's voice - but that smoothed out. The characters were believable and well-drawn. I thought I had it figured out not too far in, and then changed my mind and was right and I won't say more, but even knowing the whodunit didn't diminish the novel for me - and I was well over halfway through at that point, so I don't think it's overly obvious. 
 My one and only issue was Paul's age, which seems to mean he graduated college at least a year earlier than "normal" - and probably two years - as did his wife, but this is never mentioned. I don't know if the author just decided he had to be 26 and had to be married for 7 years and didn't do the math or what, but that was really my only problem with the story. 
 It's very visual in many places while effectively getting into various characters' emotions and motivations, all of which were believable. It's a definite recommendation from me.
