Room with a Deja View (comic story)

Summary
A murder has taken place. Committed by a member of a species that lives in the opposite direction to the timeline. Who, from its own perspective, has not yet committed the crime in question.

A locked house murder mystery where the culprit is clear from the beginning. But the process is anything but. And the Doctor lands smack bang in the middle of it all.

Characters

 * The Doctor
 * Exploits a loophole in temporal physics in order to get the full story about the murder.

Continuity

 * The Doctor is without a companion (and in fact this is one of a handful of Tenth Doctor stories in which he doesn't even work with a one-off companion), likely placing this in the post-Journey's End timeframe, although as with some of the other recent stories of this type, there is really nothing in the story to suggest it can't occur during one of the earlier companionless intervals.
 * The Doctor meets himself in his current incarnation, breaking the First Law of Time. He previously met himself in this way in DW: Day of the Daleks, DWM: The Collector and BFA: The Company of Friends, and observed himself in DW: Father's Day.''
