What Others Are Saying ...

“Pitch perfect pace and plot with a well-drawn protagonist.”
–M. Ruth Myers, Shamus Award-winning author of the Maggie Sullivan mystery series

Debbi Mack has written the Jensen character with care and irony. Her suffering from PTSD and addiction runs throughout the story, but never detracts. It takes skill to manage this, and Mack has it.
June Lorraine Roberts, Murder in Common


“Debbi Mack’s novella, Damaged Goods, is a fulfilling and exciting read and proof that the novella is alive and well. Highly recommended. I also hope we will see more of Mack’s strong protagonist, Erica Jensen in the future.”
— David Swinson, author of The Second Girl and Trigger
“A gritty, stunning portrayal of the impact and response to post traumatic stress, packaged inside a compelling mystery.”
— Frank Zafiro, author of the Charlie-316 series
“Marine veteran turned unlicensed PI Erica Jensen is a flawed and intriguing heroine in this meticulous mystery. Charlie Fox would work alongside her any day!”
— Zoë Sharp, author of Bad Turn

Fatal Connections, Debbi Mack’s second novel about PTSD-suffering ex-Marine Erica Jensen, is a twisty mystery/thriller whodunnit that builds on the sympathetic protagonist’s winning character, all the while following her through a labyrinth of lies as she endeavors to solve the brutal murders of her recent employers, a pair of married ‘influencers’ — which left her a prime suspect. … A great addition to Mack’s lawyer/sleuth Sam McRae’s canon.”
— W.D. Gagliani, author of The Judas Hit and the Nick Lupo Series

–Dale T. Phillips
Author of A Shadow on the Wall

Mystery Author Donna Fletcher Crow Says ...

“Sassy, savvy Sam McRae is back and as determined as ever to see justice done. DEEP SIX opens with a gripping hook and delivers a carefully paced legal procedural leading to a satisfying, thought-provoking ending. A read you won’t want to miss.”

–Donna Fletcher Crow
Author of A Newly Crimsoned Reliquary, The Monastery Murders

Crime and Horror Author W.D. Gagliani Says ...

“Fans of tough-talking, no-nonsense Maryland attorney Sam McRae can rejoice because she’s back in her fourth legal thriller, DEEP SIX. … Peppered with snappy, noir-tinted dialogue and Sam’s sardonic narration, DEEP SIX is a perfect whodunit for a cozy night’s reading in any season.”
–W.D. Gagliani
Author of Bram Stoker Award finalist Wolf’s TRAP
