In A Cold Case of Conscience, Annie Collins wants to unofficially review cold cases for Denver Homicide Detective Alex Frost. But solving them isn’t easy, like the arson death of a man known for his predatory behavior toward women. There are no suspects, no witnesses, and no one who is sorry that he’s gone.

Annie can’t resist the pull of a recent murder that may be connected to an old cold case. Annie and Frost aren’t sure if the two cases are connected, and the person who knows the answer isn’t talking.

Angel Cisneros, Annie’s husband, is struggling to recover after their brush with death, and his ability to tolerate the repercussions of her involvement with Frost is at an end. Annie may be forced to choose between helping Frost or concealing what she’s doing from Angel—something she’s never done.

Colorado native and former OR nurse, Helen Starbuck is an award-winning author of The Annie Collins Mystery Series. 

While she lays no claim to the coffee empires, she does fondly foster two crabby cats and a 22-year-old pampered pasture-pet horse.

When she’s not writing, you can find her dressing up like a princess and ballroom dancing with her friends or reading books about strong women and interesting men who find themselves in suspense-filled situations.
