Checkmate
The Doctor must stop a renegade Time Lord, the Monk, from altering history by preventing the Viking invasion of England in 1066, a change that would give King Harold an advantage over William the Conqueror and drastically reshape Earth's future.
The Doctor, along with his companions Vicki and Steven, arrives in 1066 Northumbria to discover a sinister plot unfolding at a seemingly deserted monastery. They soon encounter the Monk, another Time Lord, who is revealed to be a 'time meddler' intent on changing the course of history for his own amusement and perceived improvement of the future. The Monk plans to destroy the Viking fleet before it can reach Stamford Bridge, thus ensuring King Harold's army is fresh and ready to defeat William the Conqueror at the Battle of Hastings.
Vicki and Steven explore the Monk's TARDIS, disguised as a Saxon sarcophagus, where they uncover his logbook detailing his past interventions in history, including influencing Leonardo Da Vinci's designs for powered flight and exploiting compound interest in a London bank. The Doctor confronts the Monk about his reckless disregard for the 'golden rule' of time travel: never interfere with established history.
The Monk reveals his grand scheme to prevent the Norman Conquest, believing it will lead to a more peaceful and advanced future, envisioning jet airliners by 1320 and Shakespeare producing Hamlet on television. The Doctor vehemently opposes this plan, recognizing the catastrophic potential of such a significant alteration to the timeline.
Meanwhile, local villagers, manipulated by the Monk with false promises of protection, are lighting beacon fires intended to guide the Viking fleet to its doom. However, an old man warns them of the impending Viking invasion, and they question the Monk's motives. A villager confirms the presence of Vikings hiding within the monastery, turning the villagers against the Monk.
The Vikings, who were imprisoned by the Monk, escape and capture him, intending to use his plans to their advantage. The Doctor, Vicki, and Steven are captured and bound by the Vikings, but they are eventually freed by Edith, a villager who now understands the Monk's deception. The Doctor realizes the Monk still has tricks up his sleeve and races to stop him.
As the Monk attempts to signal the Viking fleet with neutron bombs, the villagers chase him back into the monastery. In a climactic confrontation within the Monk's TARDIS, the Doctor subtly sabotages the Monk's time machine by removing a crucial component, rendering it useless. The Doctor leaves a note for the Monk, who returns to find his TARDIS now the size of a sarcophagus due to the Doctor's intervention.
The Monk is left marooned in 1066, unable to further meddle with time. The Doctor, Vicki, and Steven return to their TARDIS, which had been temporarily submerged by the tide, and depart, leaving history to unfold as it should. The Viking fleet sails on, and the stage is set for the Battle of Hastings, ensuring William the Conqueror's victory and the established course of history.

The narrative beats that drive the story
The narrative opens with the Doctor confronting the Monk, who reveals his intention to destroy the approaching Viking fleet, believing this intervention will prevent the Norman Conquest and usher in a more advanced future for Earth. Concurrently, Steven and Vicki explore the Monk's TARDIS, disguised as a Saxon sarcophagus. Inside, they uncover a trove of historical artifacts and a logbook that meticulously details the Monk's past interferences, including influencing Leonardo Da Vinci's designs for powered flight and exploiting compound interest in a London bank. This discovery firmly establishes the Monk's identity as a reckless 'time meddler' and underscores his profound disregard for the integrity of established history. The Doctor vehemently opposes the Monk's elaborate 'master plan,' reiterating the fundamental 'golden rule' of non-interference with the timeline. Their debate intensifies as the Monk articulates his utopian vision of a future with jet airliners by 1320 and Shakespeare's Hamlet broadcast on television. Simultaneously, the imprisoned Vikings, Ulf and Sven, break free from their cell within the monastery, opting to remain within its walls to search for potential treasure rather than retreating. Their unexpected presence introduces an immediate, volatile, and unpredictable element into the unfolding conflict. The act culminates dramatically when the Monk, attempting to flee the Doctor's moral condemnation, is apprehended by the newly liberated Vikings. These Vikings, now aware of the Monk's 'charms' (neutron bombs), intend to co-opt them for their own strategic advantage, thereby shifting control of the destructive elements and significantly complicating the Doctor's mission to safeguard the historical timeline.

The second act escalates the conflict, introducing new threats and solidifying the Doctor's resolve. Outside the monastery, villagers, initially manipulated by the Monk, begin to question his motives after an old man warns them of the impending Viking invasion. Eldred, a villager, confirms the presence of Vikings within the monastery, turning the community against the Monk, whom they now perceive as a 'Viking spy.' Armed with this new understanding, the villagers mobilize to confront the perceived threat. Meanwhile, within the monastery, the Doctor, Vicki, and Steven find themselves bound and helpless, captured by the Vikings. As they await their fate, Vicki and Steven discuss the profound implications of the Monk's historical meddling, pondering how a changed past would rewrite all future knowledge and memories. The Doctor, though captive, remains resolute, affirming that the Monk 'must be stopped' at all costs. The Monk, now under the duress of Ulf and Sven, attempts to continue his plan to signal the Viking fleet with the neutron bombs, referring to them as 'charms.' However, as they emerge from the monastery, they are confronted by the armed villagers. This direct confrontation forces the Monk, Ulf, and Sven to retreat back inside, thwarting the Monk's immediate attempt to deploy the bombs and adding another layer of chaos to the situation.

The final act focuses on the Doctor's decisive action to prevent the Monk's historical interference and restore the timeline. Edith, a villager, frees the Doctor, Vicki, and Steven, having understood the Monk's deception. The Doctor, recognizing the Monk's persistent cunning, quickly formulates a plan to permanently neutralize his threat. He sends Steven to retrieve a pencil and paper, intending to leave a message for the Monk. Meanwhile, the Monk, attempting to evade the pursuing villagers, cunningly leads Ulf and Sven into a trap in the forest, ensuring their capture while he escapes alone. This action highlights the Monk's self-preservation and further isolates him. The Doctor proceeds to the Monk's TARDIS and, with surgical precision, identifies and removes a crucial component from the console, enduring an electrical shock in the process. This act of sabotage renders the Monk's time machine inoperable. After successfully extracting the component, the Doctor places a letter for the Monk on the altar, a final, taunting message, and then departs with Vicki and Steven. They make their way to their own TARDIS, which they find safe and sound after the tide recedes, reaffirming their commitment to allowing history to 'take its natural course.' The Monk eventually returns to the monastery, discovers the Doctor's note, and attempts to re-enter his TARDIS. To his horror, he finds it drastically shrunk to the size of a sarcophagus, its dimensional control unit disabled by the Doctor's intervention. Marooned in 1066, the Monk's meddling is definitively ended. As the Doctor's TARDIS dematerializes from the beach, the established historical events, including the Viking invasion and the Battle of Hastings, are preserved, ensuring the future unfolds as it should.
