"Mystery" was written collaboratively by Vespers Nine in just a matter of a couple of days. One evening at the home of bassist, Gricel Julie Dosal, Gricel and lead singer John Simon, came together to sort out music and melody ideas for a new song that Gricel and John wanted to form the basic foundation for. Gricel, playing the bass and working the root chord progressions and rhythms suggested by John, a good part of the basic musical song structure was sorted out that very evening. These ideas were presented to the remaining members of the band, lead guitarist, James Martinez, rhythm guitarist, Jesse Rivas, and drummer, George Dosal, at the next studio rehearsal session, where it was taken and structured even further with guitar and drum parts. James added more changes and cemented some of the guitar riffs and musical progressions to help hone and sharpen the song's structure, and Jesse and George added their respective parts to mold the song even more, better preparing it for melodies and lyrics. By the end of that particular rehearsal, the song was all but done, except for the vocal melodies and lyrics.

As the band reviewed the yet, untitled new song idea all that evening, both John and Gricel mulled over vocal melodies and potential story ideas for lyrics. Both were gravitating towards the title "Mystery" right from the very start while humming melodies, easily leading to it's eventual title. As is the usual case for VESPERS NINE, the rehearsal was recorded for future reference, and also to allow for each member to further work on any new songs in progress on their own. Using that reference allows for more ideas to form individually and then be presented to the remaining members at the following rehearsal. However, at that point in writing this particular tune, the music format was all but complete, and both John and Gricel were armed with enough to explore vocal melodies and lyrics. Gricel then took the lead in writing the melodies and lyrics, based on the song title hatched by both she and her brother, John. Playing off the title of Mystery, which lent itself to a whimsical play of words, Gricel sat down that same late evening after rehearsal and began writing the lyrics.

She spent several hours working through the lyrics, trying to form a story of love and how it often feels like a mystery to be in, or fall in love. She explored the idea of how love rarely follows any logic, but instead flows and unfolds, revealing itself as it grows. How one who lacks true romantic love, can feel somewhat lost and lacking, like one would feel in a house of mirrors, or even confused as one might feel watching the smoke and mirrors techniques of deception used by magicians to create illusions. The lyrics also play on the mystery and deception used in magician's card tricks ("making the trade - shifting the face") or card gamblers using tells and tactics to create similar deceptions to enhance their game. All these ideas were put into play to portray romantic love as being both wonderfully revealing and profound and equally deceptive and mysterious in how it all feels. One who was once lost looking for love, has found it� curiously and without denying the love's profound impact on one's life. What was an enigma, is now seemingly clear - but only seemingly, because a deep love is really always a Mystery.
