Serpents Rising

by David A. Poulsen

Published 20 October 2014

A private investigator and a journalist take on a ruthless gang in Calgary to rescue a runaway and find justice for themselves.

In 2005, journalist Adam Cullen's wife, Donna, is killed by an arsonist. In desperation after police, fire department, and insurance investigators all give up trying to find the culprit, Cullen hires private detective Mike Cobb, but he, too, is stymied. Seven years later, Cobb re-enters Cullen's life. A search for a crack-addicted teenage runaway is tangled up with Calgary's most ruthless criminal organization - and a possible lead on Donna's killer.

The parallel investigations take the two onto Calgary's meanest streets, populated by a vicious biker gang, a silky-smooth pedophile, and an assortment of people who aren't at all what they seem.

As they weave their way through long-buried secrets, Cullen and Cobb will come face-to-face with a cruelty they could never have expected ... and a killer about to strike again.

Dead Air

A Calgary Herald Bestseller!
There’s no such thing as bad press …


Ex-cop turned private detective Mike Cobb is hired as the personal bodyguard of right-wing radio celebrity Buckley-Rand Larmer, who has been receiving a string of vicious, graphic threats. Once again, Cobb recruits crime journalist Adam Cullen, this time to dig into Larmer’s past and find out who might have a grudge against him.

Soon it becomes evident that Cullen and Cobb have more to contend with than the not-so-veiled threats. When Larmer’s associate turns up dead, the broadcaster is charged with the killing, but Cullen believes the murder might be related to a series of suspicious deaths of right-wing media figures going back years. As layers of secrets and lies peel back, Cullen and Cobb have more than Larmer’s guilt or innocence to worry about. A vicious killer is out there somewhere, poised to strike again.

Last Song Sung

Published 5 May 2018
A musical cold case has Cullen and Cobb back on the beat.


On February 28, 1965, a young singer named Ellie Foster stepped into the alley behind The Depression, a Calgary folk club where she shared the bill with Joni Anderson, later to become famous as Joni Mitchell. During a cigarette break in the back alley, Ellie was forced into a car and the musicians with her were shot and killed. The investigation that followed turned up no sign of the kidnappers, and Ellie Foster was never seen again.

Now, more than fifty years after the singer’s disappearance, Ellie’s granddaughter approaches Cullen and Cobb to try to find out what happened to her grandmother. The search for the truth about Ellie Foster takes the two investigators straight into the past. They find themselves investigating a failed political assassination and discover that there are those who will stop at nothing, even half a century later, to ensure that certain secrets remain untold.
