It’s 1962, and Twentieth Century Fox is threatening to fire Marilyn Monroe. The blond goddess hires Nate Heller, private eye to the stars, to tap her phone so she will have a record of their calls in case they take her to court. When Heller starts listening, he uncovers far more than nasty conversations. The CIA, the FBI, the Mafia—even the Russians—are involved in actions focused on Marilyn. She’s the quintessential American cultural icon, idolized by women, desired by men, but her private life is... complicated...and her connection to the Kennedys makes her an object of interest to some parties with sinister intentions. Not long after Heller signs on, Marilyn winds up dead of a convenient overdose. The detective feels he owes her, and the Kennedys, with whom he busted up corrupt unions in the 1950s. But now, as Heller investigates all possible people—famous, infamous, or deeply cloaked—who might be responsible for Marilyn’s death, he realizes that what has become his most challenging assignment may also be the end of him. PI Nathan Heller returns in his first new novel in a decade, as Max Allan Collins brings to life a vivid star-studded cast, from JFK and RFK to Frank Sinatra and Peter Lawford, from Jimmy Hoffa and Joe DiMaggio to Hugh Hefner and Sam Giancana. Bye Bye, Baby is a Hollywood tale you never thought could happen…but probably did.

Long before November 22, 1963, Nathan Heller, "P.I. to the Stars," knows that a conspiracy is in the works. Several years earlier, Heller had been involved with the Kennedys, the Mob, and the CIA in the early stages of a plan to assassinate Fidel Castro. Shortly after, Heller's Mafia contact is murdered. After being interrogated by gangsters and contacted by U.S. Attorney General Robert Kennedy, Heller realizes that he may be the one person who can prevent a devastating political assassination. Only he knows all the players; only he knows why a web of conspirators has targeted the man known to the Secret Service as "Lancer," John Fitzgerald Kennedy. Rigorously researched, Max Allan Collins' Target Lancer is far more truth than fiction.

Chicago, September 1964. Beatlemania sweeps the nation, the Vietnam War looms, and the Warren Commission prepares to blame a "lone-nut" assassin for the killing of President John F. Kennedy. But as the post-Camelot era begins, a suspicious outbreak of suicides, accidental deaths, and outright murders decimates assassination witnesses. When Nathan Heller and his son are nearly run down on a city street, the private detective wonders if he himself might be a loose end... Soon a faked suicide linked to President Johnson's corrupt cronies takes Heller to Texas, where celebrity columnist Flo Kilgore implores him to explore that growing list of dead witnesses. With the blessing of Bobby Kennedy—former US attorney general, now running for Senator from New York—Heller and Flo investigate the increasing wave of violence that seems to emanate from the notorious Mac Wallace, rumored to be LBJ's personal hatchet man. Fifty years after JFK's tragic death, Collins' rigorous research for Ask Not raises new questions about the most controversial assassination of our time.
