Spoilers are precisely defined here. Rules vary by the story's medium. Info from television stories can't be added here until after the top or bottom of the hour, British time, closest to the end credits roll on BBC One. Therefore, fans in the Americas who are sensitive to spoilers should avoid Tardis on Sundays until they've seen the episode.
One audio story was released each month between January and November of 2013, each featuring a different incarnation of the Doctor. The series began in January with a First Doctor story and proceeded chronologically through the Doctors until it culminated with an Eleventh Doctor story in November. The first 10 stories were connected by way of the Eleventh Doctor sending his former selves instructions, with this incarnation of the Doctor making a mixture of subtle and overt cameo appearances in each story; the context of these instructions was explained in the final story.
The releases used only one or two narrators, similar to The Companion Chronicles. This series marked the first time the Ninth, Tenth and Eleventh Doctors, Rose Tyler, Jack Harkness and Donna Noble have been featured in audios produced by Big Finish, whose licence up until this point had restricted the company to productions using the first eight Doctors and related characters only. Night of the Whisper was also the first original-to-audio Ninth Doctor adventure. Each episode featured as its primary reader an actor or actress who played a companion, with the exception of Night of the Whisper, which was read by Nicholas Briggs.
Distribution of the series was disrupted near its end due to AudioGO going into administration in October and cancelling all future releases. Big Finish subsequently made the final volume, The Time Machine available as a download and, later in November, issued a CD release of the story. AudioGO had also planned to release an 11-disc box set of the complete series. This too was released by Big Finish in December, though quickly ran out of stock.
