Book = 'Lost' Clues?

Bad Twin, a just published novel may have mysterious links to the hit TV show Lost.
It boosts the popular therory that the island on which the cast is stranded is purgatory. Fueling the supposition: The author's name, Gary Troup (a nom de plume), is an anagram for "purgatory".

Requests to discuss Bad Twin over the past few months have been deflected, but the Lost ties can be tantalizing nonetheless. - In the Feb. 8 episode, the character Hurley is seen reading the Bad Twin manuscript, found among the wreckage of Oceanic Air Flight 815.

On the cover of the new book, under Troup's name, it reads "His Final Novel Before Disappearing on Oceanic Flight 815". On the back is a note from Hyperion explaining that Troup has been missing since the jetliner disappeared and that reason tells us that the author and his fellow travelers cannot have survived this disaster. The book jacket also lists another Troup book, The Valenzetti Equation, apparently about a mathematical eqation that can predict the apocalypse.

The plotline has no apparent link to Lost. It is a traditionally told mystery about private detective Paul Artisan hired by the wealthy Cliff Widmore to find his missing twin Zander. There are, however, details of interest to Lost fans:

There is a reference to the 17th-century British philosopher John Locke, who shares a name with one of Lost's main characters. A sloop in the novel is named "Escape Hatch". "The Hatch" is a mysterious bunker where part of Lost's action takes place. Much of Bad Twin takes place on islands real and imagined: Manhattan, Cuba, Lizard Island on the Great Barrier Reef and the fictional Peconiquot Island. At one point, Manny Weissman, Artisan's mentor, says, "Life is complicated ... It isn't like a string of numbers, you add them up, there's only one solution". A string of numbers - 4, 8, 15, 16, 23, 42 - and what they might stand for is one of Lost's mysteries.
