A Summary of Limitless by Alan Glynn
The novel opens with its protagonist, Eddie Spinola, in a state of crisis. He is hiding out in a drab Vermont motel room, the Northview Motor Lodge, with a laptop, a bottle of whiskey, and a terrible secret. The world outside his room is consumed by a fast-moving international crisis involving a potential U.S. invasion of Mexico. Eddie is a man on the run, his life in tatters, and the narrative he is compiling on his laptop is his last confession, a desperate attempt to explain the whirlwind of events that have led him to this lonely place. He resolves to tell his story from the beginning, which starts with a chance encounter on a New York City street.
That encounter is with his ex-brother-in-law, Vernon Gant, a man Eddie hasn’t seen in nearly a decade. Vernon is now a different person: slick, tanned, and wealthy, involved in some mysterious “consultancy work” for a pharmaceutical company. The two old acquaintances go for a drink, where Vernon, sensing Eddie’s creative and financial stagnation as a struggling freelance copywriter, offers him a tiny white pill. This pill, he explains, is a revolutionary new designer drug, an untested and unregulated “smart drug” that has the power to unlock the full potential of the human brain. Skeptical but curious, and desperate for a breakthrough on his stalled book project, Eddie swallows the pill, a decision that will irrevocably alter the course of his life.
The effect is almost instantaneous and transformative. Eddie’s mind becomes a supercomputer; his focus sharpens, his memory becomes photographic, and his ability to absorb, process, and synthesize vast amounts of information is exponentially enhanced. Within a single night, he has not only cleaned and organized his entire apartment but has also written a draft for his book, Turning On: From Haight-Ashbury to Silicon Valley, that he had been struggling with for months. The experience is addictive. He begins to use the drug, which he learns is called MDT-48, daily, seeing it as the key to a new, limitless life.
Eddie quickly realizes the commercial potential of his new mental capacity. He turns his attention to the stock market, mastering the intricacies of day-trading overnight. He has a natural, almost preternatural, gift for reading market patterns and making a fortune. He takes a loan from a dangerous Russian loanshark named Gennady to finance his trading and soon has amassed over a million dollars. His success doesn’t go unnoticed; he is courted by the legendary and ruthless billionaire investor, Carl Van Loon.
Carl Van Loon offers Eddie a life-changing opportunity: to help broker a secret, multi-billion dollar merger between a staid media conglomerate, MCL-Parnassus, and the brash new internet giant, Abraxas. Flush with MDT-powered confidence, Eddie accepts. He becomes an indispensable part of Van Loon’s inner circle, dazzling everyone he meets with his intellect and relentless energy. Simultaneously, he is swept up in a new lifestyle of wealth and power, buying a multi-million dollar penthouse in the Celestial Building and beginning a romantic infatuation with Van Loon’s sharp, intelligent daughter, Ginny. Eddie is at the pinnacle of a brave new world, all fueled by a little white pill.
However, the first cracks begin to appear. Eddie starts experiencing terrifying “blackouts”, temporal lapses where he acts out of control but has no memory of his actions. One such blackout leads him to brutally assault the beautiful wife of a famous painter, Donatella Alvarez, leaving her in a coma. He has no recollection of the event, only a blur of fear and confusion. As he becomes more entangled in this new life of high finance, his dependence on MDT deepens, and the periods of time he loses grow more frequent and alarming.
Eddie tries to find answers, seeking out Melissa, his ex-wife, who is Vernon’s sister. She reveals that she too had tried MDT and had suffered similar and lasting consequences. She warns him that the drug is lethal, that his supply is finite, and that he is heading for a catastrophic physical and mental collapse. This conversation forces Eddie to confront the true nature of his predicament: he is a junkie, and the drug that has given him the world is now destroying him from the inside. His obsession with MDT leads him to an old address book belonging to Vernon, which contains the names of other clients. When he contacts them, he finds an epidemic of strange illnesses and deaths, all former MDT users whose supply has run out.
Desperate, Eddie discovers that the drug was manufactured by the powerful pharmaceutical corporation Eiben-Chemcorp and that its development is linked to another product, Triburbazine, which is currently the subject of a major product-liability trial. He contacts the plaintiff’s lawyer, Dave Morgenthaler, hoping to use his knowledge of MDT as leverage to either blackmail the company into supplying him or to trade the information for a steady source of the drug. This is a catastrophic mistake. He is now a liability.
The final act of the novel unfolds with relentless speed. While at the press conference announcing the historic merger he helped broker, Eddie receives a call from Morgenthaler. He sees his own face flash on the television news, a face that is now connected to the Donatella Alvarez assault. The walls are closing in. A phone call from an unknown man confirms his worst fears: his supply of MDT was never his to possess; it was all part of an elaborate corporate “experiment,” and now that he has become a threat by contacting Morgenthaler, the experiment has been terminated. When he returns to his new penthouse, he finds it ransacked and his remaining stash of the drug and its secrets gone.
The next day, Gennady, the relentless loanshark, arrives. Now aware of Eddie’s connection to the corporate world, he tries to blackmail him into giving up the source of his “smart drug” supply. In a moment of sheer desperation and terror, as Gennady brutalizes him, Eddie grabs a kitchen knife from a broken box on the floor and stabs him to death. In the chaos, he takes the remaining MDT pills from Gennady’s pocket. Realizing he is now a murderer and that the police are closing in (having seen the press conference and identified him as the man connected to the Alvarez attack), Eddie makes a plan.
His final act is one of profound, tragic nostalgia. He flees the city with the money Gennady was trying to extort and uses his last few remaining MDT pills for one final burst of clarity. He drives to the quiet suburban home of his ex-wife, Melissa, in Mahopac. He doesn’t want to see her. Instead, he leaves the briefcase full of money on her doorstep for her and her two young daughters, a guilt-ridden attempt to make amends for a past he can never repair. After a brief, heart-wrenching exchange with her daughter Ally, he flees again.
Eddie continues north, now completely out of the drug and descending into a final, agonizing withdrawal. He checks into the Northview Motor Lodge in Vermont where the novel began. He is a wanted man, a fugitive, his body and mind shutting down as the effects of the MDT wear off for good. As the world outside his motel room is consumed by the news of the U.S. invasion of Mexico, Eddie writes his story, a final confession on his laptop. He is left with the remnants of his life, a bottle of whiskey, and a bottle of paracetamol, facing the grim, inevitable reality of his demise. The novel ends with Eddie struggling to save his file, a final, futile act of trying to preserve the narrative of a life that has been completely and utterly destroyed.
