Eternal Lies is a 2013 role-playing game adventure campaign by Will Hindmarch and Jeff Tidball with Jeremy Kelle, published by Pelgrane Press for Trail of Cthulhu.

[1][2] The print edition was also published in a special pre-release bundle with the soundtrack album by James Semple and a PDF.

There are a number of excellent twists and turns in the story, as the players confront a worldwide cult and the alien forces behind it and take on an escalating quest to save humanity.

There's a lot of material here, but the writing is top notch and the book is a real pleasure to read.

Despite the incredibly high esteem in which I hold the Masks of Nyarlathotep, however, I’m of the opinion that Eternal Lies is even better.
