The Truthseeker

The Truthseeker is Dee Henderson's third installment in the O'Malley series, featuring as protagonists Lisa O'Malley and Marcus's friend and U.S. Marshal partner Quinn Diamond.

Lisa, I believe, is a forensic pathologist. She worked with Marcus on the murder case Shari was witness to in the last book. She is now taking on a new challenge: solving cases that had been shelved decades ago because no one could discover who the murderer was.

Quinn, though he's a Christian and Lisa is not, is trying desperately to get Lisa to agree to a date with him and has been trying since the last book. But there's a bigger problem here than just stubbornness on Lisa's part; Quinn has dated two other women in the O'Malley family (Jennifer and Kate) and even accidentally reveals later that he asked out Rachel too. Lisa is definitely not happy about being asked out last.

Things get complicated in this book as Henderson juggles a plotline that follows many different strings. Lisa's past, the Christianity that seems to be taking hold of her family one by one, the stalker that shows up in Lisa's life and burns her house with all her pets trapped inside, the romance also taking hold of her family one at a time, and (worst of all) Jennifer's cancer that has recently become public knowledge among the close-knit family of seven.

Oh, and although it doesn't seem like it from the description I just gave, Quinn is more than just a side character. He takes an active part in just about every single turn in Lisa's life.
