The twists and turns will keep you guessing to the end and just about the time you think you have it all figured out she surprises you by steering you away with another clue. The author is always keeping you guessing as to where the story will lead you next. Ms. Cohen has just joined the list of my favorite authors and I look forward to reading the other books she has written. I hope you find Hanging by a Hair as great as I did.
Marla Vail, owner and operator of the salon Cut N’ Dye, and her husband, Detective Dalton Vail a homicide investigator, moved into Palm Valley recently following their recent marriage. They are attending their first Home Owners Association meeting when Dalton stands up to the Board president, Alan Krabber, for breaking the association rules after forcing another resident to comply with one Alan himself was breaking. After the meeting the man makes a suggestive offer to Marla within Dalton’s hearing followed by some very bigoted and derogatory remarks and Dalton loudly puts Alan down. Unfortunately for Marla and Dalton, Alan was their neighbor and a bigot and religious fanatic. To say life has its trials and tribulations in Palm Valley is an understatement.
The following day Alan hires someone to erect a fence and plant some trees. The problem is that he is having the fence put on the Vail’s side of the property line and is planning on planting trees whose roots will quickly grow into the pipes of their sprinkler system. After another loud shouting match between Dalton and Alan, which was heard by neighbors, Dalton threatened to go to the zoning board regarding Alan’s lack of property survey, building permits, and the workers’ failure to have a business license. The following day Alan Krabber is found dead, hanging from his second story banister railing. Dalton is removed from the case and neighbors are quick to tell the police of Dalton’s confrontations with Alan and the heated words they exchanged. Dalton is one of many named a person of interest. How on earth was such a vile man elected president of the HMA board?
Suddenly their quiet community is a hotbed of liars, thieves and a murderer who has not finished. Marla must be careful as she tries to prove to her husband’s new partner that he had nothing to do with the murder of Alan. The killer is watching and Marla is starting to become an unwanted nuisance that needs to be permanently removed. The body count is rising and Marla is finding more suspects every day. Can she figure this out, prepare the first Seder in their new home, cope with her mother and her on again, off again relationship with her crass and obnoxious boyfriend, and all the drama going on at the Cut N’ Dye?
Hanging by a Hair is the latest in the Bad Hair Day Mystery series, but is written in such a way you can easily read as a standalone novel. Not so good for me is the fact I fell in love with Marla and Dalton and their extended family and friends. Now I need to get the other books in the series to see if they are all this fascinating. The characters in the book are very well developed and balanced with enough good and bad traits to make them believable. Nancy Cohen has provided numerous clues, both blatant and subtle, to keep you invested in the story.
