'You're The Worst'
"Constant Horror And Bone-Deep Dissatisfaction"
"The Lazarus Protocol" was a movie directed by Ty Wyland which featured a song on the soundtrack by Gretchen's PR client, rapper Honey Nutz.
The title of the movie is similar to the tried and true formula of the Robert Ludlum novels like "The Bourne Identity", "The Rhinemann Exchange", "The Osterman Weekend", etc. (The only major disappointment in sales came when he left the formula - "The Road To Gandolfo".)
But we don't have to say that "The Lazarus Protocol" was based on a book by Ludlum's televersion. There was another writer seen only in Toobworld who must have been patterned after Mr. Ludlum - Richard Laidlaw.
"Let's Steele A Plot"
Richard Laidlaw wrote thrillers with the same type of title - one seen in the episode was "The Dickenson Dossier". He hired the Remington Steele Detective Agency to ferret out the embezzler in the Mystery Writers' Guild who stole the group's fortune.
I could see "The Lazarus Protocol" as being one of his tomes. And as for the subject matter?
"The Lazarus Experiment"
I wish I could say the original book was based on the scientific debacle caused by Professor Richard Lazarus. But that happened in 2008 and while it's pozz'ble, just pozz'ble that a book was written about those tragic events (and then a movie made for release in 2014), I don't think Richard Laidlaw would have penned it: Laidlaw died in 1988, twenty years before Professor Lazarus' failed experiment regarding immortality. (I usually assume TV characters die around the same time as the actors who played them, if they were concurrent.)
