The Recommended Reading Order for Sam Casey
To get the most out of the Sam Casey mysteries, you should read them in publication order. While the individual homicide cases and supernatural puzzles are self-contained in each novel, the overall character development, romantic progression, and unfolding mythology of Sam’s heritage are highly serial. Reading them out of order will spoil major relationship milestones—particularly between Samantha and detective Jake Mitchell—as well as the shifts in her psychic abilities.
Sam Casey Books in Publication Order
Written by S.D. Tooley, the series spans eight core novels, beginning with Sam's debut in 1999 and concluding her main character arc in 2017. Here is the complete order of the main series:
- When the Dead Speak (1999) – Detective Samantha Casey is introduced along with her eerie gift: she can hear the final whispers of the deceased. In this debut, she investigates a soldier's body discovered inside a concrete pillar clutching a mysterious lightning bolt pin.
- Nothing Else Matters (2000) – Taking a forced leave of absence, Sam finds herself drawn into a high-stakes casino murder investigation that is closely tied to a contract killer known as Sparrow.
- Restless Spirit (2002) – Sam tackles a painful cold case to prove the innocence of a man convicted of a seventeen-year-old crime, earning the series critical acclaim.
- Echoes from the Grave (2007) – Sam’s psychic abilities are put to the test when she begins hearing the voices of victims from beyond the grave, leading her down a path of dark family secrets.
- What Lies Within (2010) – Sam must dig deep into a complicated web of secrets in Chasen Heights as old threats resurface, forcing her to rely on both her police training and her Sioux heritage.
- Destiny Kills (2012) – A rash of bizarre suicides, all connected by the cryptic word "destiny," points to a serial killer who sets their sights directly on Sam.
- The Tunnel (2013) – Working as an investigative consultant with fading psychic abilities, Sam faces a deeply personal case when a young boy discovers a hidden tunnel and her husband's gun is linked to a crime.
- Buried Secrets (2017) – The eighth core novel in the series sees Sam Casey facing long-buried truths that threaten to destroy her life in Chasen Heights once and for all.
The Chase Dagger Crossover: Killer Double
In 2023, S.D. Tooley thrilled long-time readers by publishing Killer Double. This special crossover novel unites characters from the Sam Casey series with the Chase Dagger series, which Tooley writes under the pen name Lee Driver.
In Killer Double, Sam Casey and Jake Mitchell team up with private investigator Chase Dagger and his shapeshifting partner, Sara Morningsky. Together, they investigate a series of bizarre crimes spanning South Carolina and Indiana, where fingerprints belong to a serial killer dead for more than two decades. It is highly recommended that you finish the main Sam Casey series before diving into this crossover to fully appreciate the character dynamics.
What to Know Before You Start
Set in the fictional Chicago suburb of Chasen Heights, the series centers on Samantha "Sam" Casey, a Native American detective sergeant. Sam’s maternal Sioux heritage plays a vital role in the series; she inherited her mediumship abilities from her mother, Abby. Instead of clean, convenient psychic visions, Sam hears fragmented, chaotic sounds and whispers from the dead, which she must carefully piece together using logical detective work.
Readers should expect a compelling blend of traditional police procedural grit and occult detective mystery. While the tone is suspenseful and sometimes chilling, the warm, developing romance between Sam and Jake Mitchell, alongside her complex family dynamics, gives the series a grounded, human heart.
