When delving into the vast tapestry of any prolific author's creations, especially one woven from more than a dozen novels, it becomes challenging to draw sweeping conclusions. However, a striking pattern emerges in Clark's fiction, particularly concerning her character portrayals. Typically, her characters, whether villainous or heroic, exude wealth and allure. Indeed, in the world of Let Me Call You Sweetheart, affluence serves as the measure of worth. Here, the "best" is synonymous with the richest. This elite circle is not defined by morality or industriousness; even the most nefarious individuals can be part of this distinguished group. Instead, best signifies the social echelon most coveted. Perhaps this theme resonates with Clark's readers, who relish fantasies of opulence and leisurely companionship with the affluent. Nevertheless, this element of her storytelling can feel disconcerting, especially in a narrative that champions women's accomplishments in the workplace and broader society. The true essence of the heroine, Kerry, is her fervent goodness, not her social rank, the wealth enveloping her friends, or her stunning beauty.

Spending time with Kerry McGrath is a delightful experience. Though she is undeniably lovely, her thoughts seldom linger on her appearance. She devotes her energies to others, with her daughter naturally occupying much of her attention. Yet, she's far from a supermom—she struggles with fulfilling all her desires for her child. Her role as a prosecutor holds significant value, and she openly aspires to be a judge, drawn by the prestige it brings. However, her actions reveal that both career and prestige bow to her unwavering commitment to justice. She refuses to be easily swayed; Reardon's claims of innocence seem credible, yet fragile against the amassed evidence. Only through diligent and meticulous investigation does she gradually consider the possibility of Reardon's innocence.

A powerful heroine shines brightest when surrounded by compelling supporting characters. As a romantic interest, Geoff Dorso fulfills this role admirably. Although he is charming, intelligent, and shares her zeal for justice, Kerry remains steadfast in her beliefs. If she suspects Reardon, Geoff's client, is guilty, she won’t hesitate to jeopardize their promising relationship to see justice served. Geoff is a likable character, yet adversaries also contribute to a well-rounded protagonist. Jonathan, supposedly her ally and confidant, would abandon her should she become a political burden; by chapter 30's end, he advises the governor to stall her judicial nomination. This starkly contrasts with Kerry's resolute pursuit of righteousness. She bravely investigates the innocence of a convicted murderer, unafraid of the potential professional and political fallout. Unlike Jonathan, she adheres to her principles. Her husband, Robert Kinellen, exemplifies betrayal: he lies, neglects, and continually lets down their daughter, Robin, whom he supposedly cherishes. He’s willing to sacrifice anyone, Robin included, in pursuit of wealth and status. While he is a lawyer driven by greed, Kerry is one propelled by justice. Dr. Smith, who revels in crafting beauty, simultaneously seeks to dominate it, relishing the adoration of his creations. He disregards the individuality of women beneath the surgical veneer; Barbara and others transformed to resemble Suzanne bolster his belief that altering looks alters personality. Much like Pygmalion, he is enamored with his own artifice. In contrast, Kerry dedicates herself to uncovering true motivations, seeking to liberate the genuine beauty she encounters.

Let Me Call You Sweetheart teems with fascinating characters, perhaps none more intriguing than Jason Arnott. While he privately muses, "Do I think Skip Reardon killed Suzanne? No, I don't, Ms. McGrath," he refrains from voicing it. He harbors many secrets. He exudes a complex dichotomy: capable of profound appreciation for art and beauty, yet indifferent to people. To him, individuals are mere curiosities, occasionally indulged with his expertise in rare antiques, but ultimately manipulated to discover their most prized possessions and the opportune moment to pilfer them. He is the disruptive element in the "best" society; amidst the wealthy, he stands as the most astute, cultured, and open-minded—and yet, he is a thief.
