Another excellent Sean O'Brien thriller. A woman who helped send a man to prison for murder seven years ago by not confirming his alibi is dying and hires Sean to help free him. The suspected guilty parties don't want to be caught, even if it means killing again. Tom Lowe is at his best when he keeps O'Brien near Florida. A wonderful ensemble cast of friends and family is always a plus. Read on my new Kindle gifted to me by my daughter. So far, I like the Kindle,I can read and hold a cigar or a drink.

The story flows well and has the right amount of action to keep it interesting. I didn’t like that there were two characters who were thanked and praised for coming clean years after their lies put people in Prison. One because she was dying and one because he was confronted. They both lied and ruined lives. Also, Sean in an attempt to bring out a killer, creates a news story with witnesses interviewed. One witness is killed because of the news story and there is no remorse. It only becomes another clue.

More stars needed

Five stars are not enough for this book. On the one hand, the dangerous, frightening parts of the story have you concerned about what’s going to happen and on the other hand, the heartwarming parts of the story have you cheering for the good guys. As always, spending time with Sean, Wynonna, Angela, Connor, Nick and Dave is like being with old friends. However, the very best part is spending time with Max!

A good plot but the dialogue was wooden more like prose narrative than conversation,however, it was fair and complex enough. the characters are a bit flat like their Dial alicia, a bit. one-dimensional the good characters who he tried to make more complex did their bad thing in the past and are on the good side now.

Heart warming

Thank you Tom for once again taking me on a beautiful journey, one with some heart stopping moments. There are times with our belief in God and belief that there are good people that give us hope that life is to be cherished.

But with the end of this beautiful case you have left us with a question regarding Dave which I am hoping that isn’t serious. ❤️🇦🇺

This series just keeps getting better!

I think I’ve read every Sean O’Brien that Tom Lowe has written. This may be his best yet! The setting (in our area of Florida) and his descriptions of the area makes me feel like I’m right there. I Love the characters. Like visiting old friends.

Good read. Good to know that Sean O'Brien is still bulletproof and can leap tall buildings with a single bound!😀
