Devil in a Blue Dress is the first novel in Walter Mosley’s acclaimed Easy Rawlins mystery series. Set in post-World War II Los Angeles in 1948, the story follows Ezekiel “Easy” Rawlins, a Black war veteran who finds himself drawn into a dangerous world of murder, politics, and racial tension, all while trying to survive in a society that’s not built for men like him.

At the start of the novel, Easy has just been fired from his job at an aircraft factory. He’s short on money and unsure of how he’ll make rent on his small home in Watts a home that represents everything he’s worked for since leaving the war behind. With few options, Easy finds himself sitting in a bar owned by a friend, where he’s introduced to a mysterious white man named DeWitt Albright.

Albright offers Easy a job that sounds simple: find a woman named Daphne Monet, who has gone missing. She’s described as beautiful, light-skinned, and always wearing a blue dress. Albright says she has a history with some important people and they just want to find her. Easy is suspicious, but the promise of a quick paycheck and the risk of losing his house push him to take the job.

As Easy starts looking for Daphne, he quickly realizes that nothing about this case is simple. Daphne used to be engaged to a wealthy white mayoral candidate named Todd Carter, but the engagement mysteriously ended. Her disappearance seems to be tied to a man named Richard McGee, a gangster, and other shady figures in LA’s Black and mixed-race communities. Everyone seems to have a different story, and none of them add up.

While following Daphne’s trail, Easy visits several bars and dives deep into neighborhoods most white investigators wouldn’t dare go. He reconnects with old acquaintances some helpful, some dangerous. One of the key people he encounters is Mouse Alexander, a childhood friend from Texas. Mouse is charming but incredibly violent, and Easy knows calling him in will almost certainly lead to trouble. Still, when things get too dangerous, Easy brings Mouse to LA to help him out.

Bodies start piling up. People connected to Daphne both friends and enemies are murdered. Easy realizes that there’s more at stake than just a missing person. There are secrets involving race, power, blackmail, and identity. It turns out that Daphne Monet is not who she appears to be. She is actually Ruby Hanks, a mixed-race woman passing as white to move through high society. Her real identity, if revealed, would destroy Carter’s political ambitions.

The more Easy digs, the more danger he faces. He’s beaten by police, followed by criminals, and forced into increasingly deadly situations. He learns that DeWitt Albright isn’t just some private eye he’s a violent fixer hired to clean up loose ends, and he’s willing to kill anyone who stands in his way. Easy is now caught between powerful white men trying to keep secrets buried and members of his own community who are afraid or complicit.

Eventually, Easy finds Daphne. She explains the truth: she stole some incriminating photos that would reveal her identity and ruin Todd Carter’s mayoral campaign. She claims she loved Carter, but his family forced her out when they learned the truth about her race. She’s been on the run ever since, trying to survive and protect herself from Albright and others hunting her down.

As Easy tries to help Daphne, the situation spirals. Mouse steps in and kills several men, including people who threatened Easy and Daphne. Mouse’s presence, while terrifying, ends up saving Easy’s life. Despite Mouse’s brutality, there’s a strange loyalty between the two men one forged long ago in Texas, and now tested in the blood-soaked streets of LA.

In the end, Easy manages to outsmart DeWitt Albright and survive the fallout. Daphne gives the damning photos to Easy, who then returns them to Todd Carter. In exchange, Carter pays Easy off and drops out of the mayoral race, choosing to avoid public scandal. The entire matter is swept under the rug by the powerful, but not without a cost.

Easy, though alive and paid, doesn’t walk away unchanged. He sees firsthand how racism, power, and corruption infect every layer of society. Even when he wins, the rules are crooked. Still, he also discovers something else: he’s good at solving mysteries, and people talk to him in ways they wouldn’t talk to a white detective. There’s a place for someone like him in this shady world not just to survive, but to carve out power of his own.

The novel closes with Easy paying off his mortgage. He’s safe in his home again, but something has changed. He no longer sees himself as just a man trying to make a living he’s now a private investigator of sorts, someone who can navigate both the Black and white worlds of Los Angeles, even if it means walking a dangerous line between them.
