Erin Clark Brings Advertising Insight to The Etiquette of Murder

For Erin Clark, the move from advertising leadership to fiction is less a departure than a new application of familiar skills. Her debut murder mystery, The Etiquette of Murder, brings together several threads from her professional and personal life: a close reading of human behavior, an interest in social graces, experience balancing creativity with analysis, and a lifelong connection to Chicago.

The result is a cozy whodunit set against the city’s Gold Coast, a setting suited to a story attentive to appearances, expectations, and the revealing details of social interaction. The book is now available through Amazon and BarnesandNoble.com, as well as through bookstores by request.

From brand narratives to a mystery plot

Before turning her attention to fiction, Erin built a career in marketing and brand leadership spanning more than 25 years. She spent much of that career at J. Walter Thompson, where she rose to Senior Vice President and Group Management Director. In that role, she led the development and implementation of campaigns for Fortune 500 companies.

Advertising required her to work at the meeting point of art and science. Creative ideas had to be memorable, but they also had to respond to research, business objectives, and close analysis of what people wanted. That combination offered a practical education in motivation: how people present themselves, what captures their attention, and which emotional cues can shape a response.

Those observations now serve a different kind of narrative. Mystery fiction depends on carefully managed information, distinctive personalities, plausible motives, and the tension between what characters reveal and what they conceal. Erin draws upon the high-drama advertising environment she knew—including its volatile blend of creative ambition and data-driven decision-making—to shape the characters and social dynamics of her first novel.

The significance of social intelligence

The title The Etiquette of Murder points to another important part of Erin’s background. She is a certified etiquette consultant, a qualification that complements her longstanding interest in how people behave around one another. Etiquette can be understood as a collection of rules, but it can also illuminate relationships: who feels at ease, who understands an unspoken expectation, and who gains or loses standing when conventions are tested.

That perspective offers fertile ground for a mystery. Polished manners do not necessarily disclose private intentions, and an apparently orderly gathering can contain competing desires or unresolved tensions. By bringing social intelligence into the framework of a cozy whodunit, Erin explores the distance between a composed exterior and the motives operating beneath it.

Her advertising experience reinforces that focus. Campaign development involves decisions about language, imagery, timing, and audience perception. Erin’s work included award-winning campaigns and breakthrough work credited with introducing the term “Brainfreeze” into popular culture. Such assignments called for both broad strategic thinking and attention to the precise detail that makes an idea memorable—disciplines that also matter when constructing clues, scenes, and turning points.

Chicago as more than a backdrop

Chicago provides the novel with a sense of place rooted in Erin’s own lifelong connection to the city. For The Etiquette of Murder, she selected the Gold Coast as the story’s glittering backdrop. Its atmosphere supports the novel’s interest in social presentation while giving the mystery a specific urban setting rather than an abstract stage.

This connection between setting and theme reflects the broader way Erin has approached her transition into authorship. She is not leaving her prior experience behind. Instead, she is translating knowledge acquired through marketing, leadership, etiquette, and observation into the demands of contemporary fiction.

A creative chapter grounded in experience

Erin’s path demonstrates how professional expertise can remain relevant when the form of the work changes. Advertising campaigns and mystery novels serve different purposes, yet both require an understanding of audience attention, narrative momentum, and the significance of a well-placed detail.

Alongside her marketing and writing work, Erin is an ASPCA Guardian Member and an advocate for animal welfare. Together, her interests reflect an outlook attentive to behavior, relationships, and responsibility. With The Etiquette of Murder, she brings those varied dimensions into a new creative chapter—one grounded in the strategic discipline of her former career and shaped by the possibilities of storytelling.
