The Luminous Face

In Short

When Robert Gleason is found shot dead in his Washington Square apartment, a cryptic phone call to a doctor’s office leaves the police with a perplexing puzzle: the victim apparently called for help after receiving a fatal bullet. Detective Prescott struggles through a tangled web of suspect friends, forged letters, hidden chorus-girl connections, and missing fur collars. As suspicion shifts relentlessly among an artistic suitor, a distressed socialite, and a secretive brother, private investigator Pennington Wise and his sharp assistant Zizi step in. Together, they unravel a cold-blooded conspiracy built on stolen identity, calculated alibis, and hidden motives.

The Story

The mystery begins with an idle argument among acquaintances about the nature of murder and the statistics of unsolved crimes. Within hours, the debate becomes grim reality. Nurse Jordan, answering calls at Doctor Davenport’s office, receives a faint, desperate telephone message from Robert Gleason claiming he has been shot at his Washington Square apartment. When Doctor Davenport and the authorities arrive, they break down the door to find Gleason dead on the floor with two bullet wounds. The initial mystery hinges on an apparent impossibility: how could a man suffering from an instantly fatal gunshot call his doctor to report his own murder?

Detective Prescott takes charge of the investigation and immediately finds himself navigating a maze of conflicting testimonies and guarded secrets. Gleason’s sister, Millicent Lindsay, along with her children Phyllis and Louis, are thrust into the center of the tragedy. Phyllis admits to having visited Gleason’s room recently, while a stray cheap fur collar found at the crime scene suggests the presence of an unknown woman. Meanwhile, suspicion falls heavily upon Philip Barry, an intense artist in love with Phyllis. Prescott discovers a typewritten letter in Gleason’s desk, signed by Barry, threatening dire consequences if Gleason does not cease his attentions to a mutual female acquaintance. Barry fiercely denies writing the letter, despite his genuine signature at the bottom, claiming he is being framed.

As Prescott hits dead ends, the emotional strain pushes the Lindsay family to the breaking point. Phyllis acts erratically, attempting to raise large sums of cash and eventually fleeing to the home of her friend Ivy Hayes to avoid further interrogation. To protect Phyllis, Barry goes so far as to falsely confess to the murder, but the police recognize his claim as a desperate ploy. Frustrated by the lack of progress, the family turns to the renowned private detective Pennington Wise and his perceptive partner, Zizi.

Wise systematically re-examines the evidence and interrogates every figure in Gleason’s circle, including the suave, wealthy Manning Pollard, who had previously voiced open hatred for the dead man. Wise unravels the puzzle of the threatening letter: it was written in vanishing ink above a real signature that Barry had innocently provided for a club petition, after which the murderer typed the threat over the blank space.

The final breakthrough comes from Zizi, who notices a discrepancy involving a wrist watch and tracks down Pollard’s secret double—his twin brother, Taylor. Pollard had engineered a cast-iron alibi by having Taylor impersonate him on the night of the crime while Pollard himself murdered Gleason. Pollard’s motive was twofold: Gleason knew the shameful secret of Pollard’s birth and was using it to blackmail him into giving up Phyllis, while Pollard also sought to secure the fortune attached to Gleason’s death. Exposed by Wise and Zizi, Pollard confesses to the crime, clearing Barry and leaving Phyllis free to reunite with the man she truly loves.

How It Unfolds

A sinister prophecy A group of gentlemen at a club discuss unsolved homicides, debating whether a woman ever possesses the nerve for violence and how few murderers are ever caught. Hours later, one of their acquaintances is found shot to death in his own home.

The dying message A tired doctor's nurse answers a jangling telephone to hear a dying man gasp that he has been shot at Washington Square. When help arrives at the apartment, Robert Gleason lies dead, creating an immediate paradox regarding how a dead man could place a phone call.

The net of suspicion Detective Prescott begins interviewing Gleason’s acquaintances and family, uncovering a web of petty grudges, strange disappearances, and a cheap fur collar left in the victim’s room. Friends and relatives offer evasive answers about their whereabouts on the night of the crime.

The forged threat Prescott discovers a typewritten letter in Gleason's desk containing a direct threat signed by the artist Philip Barry. Though the signature is indisputably his, Barry passionately denies ever writing or seeing the document, insisting he is the victim of a frame-up.

A desperate flight Overwhelmed by interrogation and secretive financial troubles, Phyllis Lindsay flees her home to hide with a friend, prompting the police to view her departure as a tacit confession. In a desperate bid to shield her from arrest, Philip Barry attempts to take the blame himself.

Unmasking the double Pennington Wise and Zizi enter the case, uncovering the trick of the vanishing ink used to fake the threatening note. Zizi follows a suspicious lead to uncover Manning Pollard's secret twin brother, exposing the elaborate alibi that hid the true killer.

In Its Own Voice

“I’ve no head for statistics,” he went on, idly drawing caricatures on the margin of his evening paper as he talked, “but I think they say that only one-tenth of one per cent, of the murderers in this great and glorious country of ours are ever discovered.”

(Philip Barry lightheartedly dismisses the efficiency of criminal investigations hours before becoming the prime suspect in one.)

“No, of course not. Nor any reason to mention them to the Lindsays. They’ll know all there is to know. You can’t fool ’em. Miss Phyllis is as wide-awake as they come, and the Mrs is nobody’s fool.”

(Detective Prescott and attorney Belknap assess the sharp intelligence of the women involved while searching the victim’s private papers.)

“A cleverly contrived thing. It was originally written in vanishing ink and Barry signed it in real ink. Then, when the vanishing ink vanished, the perpetrator of the precious scheme filled in the typed letter above the signature.”

(Pennington Wise explains to Zizi the ingenious mechanical trick used to frame an innocent man for murder.)

What It's Really About

Beneath its classic parlor-car setup, the novel probes the deceptive nature of surface appearances and the fragility of high-society reputations. It contrasts the rigid, literal-minded methods of traditional police work with a more flexible, psychological approach to human behavior. The story asks how easily an innocent person can be trapped by engineered evidence when institutional justice values swift conclusions over thorough truth. It also explores the lengths to which individuals will go to protect social status and family secrets, demonstrating how fear of public exposure can drive a person to orchestrate calculated violence.

Why Read It Today

Fans of puzzle-box golden age mysteries will appreciate the story's light-footed pace and classic detective tropes. Carolyn Wells delivers a cleanly plotted whodunit that relies on clever physical gimmicks—like chemical inks, staged phone calls, and secret doubles—rather than grim violence. The writing reflects the cozy, theatrical tone of early twentieth-century American mystery writing, where high-society drawing rooms serve as the stage for high-stakes deception.

Readers should be prepared for the narrative conventions of its era, including somewhat melodramatic dialogue, rapid-fire coincidences, and characterizations that prioritize plot mechanics over deep psychological realism. The police work often appears naive by modern forensic standards, existing primarily to highlight the brilliant deductions of the private sleuth. Yet for those who enjoy cracking a carefully constructed criminal puzzle alongside a pair of persistent investigators, the novel offers a swift, engaging, and delightfully intricate slice of period detective fiction.
