Introducing LaVonne Griffin-Valade’s debut novel, and the first in the gripping Maggie Blackthorne series.


Fans of Sheriff Walt Longmire will fall in love with Sergeant Maggie Blackthorne, the spirited protagonist with a tragic past and an acid wit.


"...an engrossing neo-Western thriller in which justice and morality clash." —Foreword Reviews


When Maggie Blackthorne returns to her hometown after nearly twenty years to serve as an Oregon State Police Sergeant, she expects to deal with the usual suspects—drunk drivers, oxy slingers, and the occasional rural scofflaw.


But after she stumbles upon the bullet-ridden bodies of twin brothers, she realizes she’s stepped into something much more sinister. With little homicide experience, Maggie and her partner, Trooper Hollis Jones, find themselves thrust into the murder investigation.


And when a third man turns up dead, Maggie fears it’s only a matter of time before the killer strikes again. As they race to piece together what happened, Maggie and Hollis discover a tangled web of theft, deceit and deals gone bad.


Faced with multiple motives and several persons of interest, Maggie and Hollis finally catch a break—but are they willing to risk everything to put the murderer behind bars?

Murderers Creek

Sergeant Maggie Blackthorne's latest case gets personal as she risks everything to prove her innocence and bring a killer to justice.


The highly anticipated second novel in the compelling Maggie Blackthorne series.


After an unexpected and unpleasant visit from her ex-husband, Oregon State Police Sergeant Maggie Blackthorne is called to a grisly crime scene. Her ex has been found dead—the victim of a vicious attack.


Her earlier confrontation with the deceased places Maggie squarely on the list of suspects, and she is soon the subject of an internal investigation. Desperate to clear her name and uncover the truth, Maggie and her partner, Trooper Hollis Jones, have no time to waste.


With a couple of townspeople acting suspiciously, reports of missing or stolen property, and evidence of drug deals gone bad, the case is proving to be a difficult one to crack. And just when Maggie and Hollis think they’ve finally caught a break, the lone eyewitness turns up dead.


As the personal and professional pressure mounts, Maggie struggles to catch a remorseless killer who has nothing to lose. And one wrong move could cost Maggie her career... or her life.


Murderers Creek is a can’t-miss read that will keep you captivated until the very last page.

About LaVonne Griffin-Valade

LaVonne Griffin-Valade was born and raised in the high desert country along the John Day River of eastern Oregon. It’s a vast and luminous landscape made up of wind-sculpted fossil beds, pine and juniper forests, grasslands, indigo mountains, and river-fed valleys—a place that stoked her imagination and inspired her to become a lifetime writer of short stories, essays, poetry, and novels.

LaVonne has carried her love of language, story, and imagery wherever life has taken her, whether it was the eastern Oregon high desert, the islands of Saipan, Guam, and American Samoa, Alaska, Montana, Wyoming, New York, Washington D.C., or western Oregon’s green, lush Willamette Valley. She has participated in dozens of classes and workshops offered by fiction writers, poets, memoirists, and essayists including John Beer, David Biespiel, Emily Chenoweth, Paul Collins, Martha Gies, Karen Karbo, Nam Le, Michael McGregor, Tom Spanbauer, Kim Stafford, Lidia Yuknavitch, and Leni Zumas.

Along the way LaVonne earned a Bachelor’s degree in Humanities (English/writing focus) from Western Oregon State University and was an elementary school teacher for a time. Switching gears, she worked with homeless and runaway youth for several years connecting them with shelter and providing life skills training. She went on to earn a Masters of Public Administration from Portland State University while working for the Northwest Regional Educational Laboratory in Portland, Oregon where she trained educators in educational equity and penned various professional articles.

In her penultimate career change, LaVonne became a government performance auditor in the Multnomah County Auditor’s Office in Portland, first as a staff auditor for eight years and then as the elected Multnomah County Auditor. She then ended her long auditing career as the elected Auditor of the City of Portland. After leaving office, she pursued an MFA in fiction writing from Portland State University and graduated in 2017.

LaVonne’s personal essays have appeared in Oregon Humanities Magazine, and her short story “Eureka” was published in the 2019 Clackamas Literary Review. Based on an excerpt of DEAD POINT, she was a finalist for the 2018 Fellowship for Emerging Writers at Fishtrap’s Writing and the West.

LaVonne lives in Portland, Oregon and works as a full-time writer.
