Synopsis: Jamie destroys the worldshaper at the expense of his life. The Time Lords, ever-sensitive to the Doctor's meddling ways, show up to curb the Doctor's proclivities.
Notes: This issue marks the only documented instance of Jamie's death. There being nothing to contradict it, this is a Very Important Issue
Unfortunately, it's a story that bends, but doesn't necessarily break, televised continuity on several fronts. Some fans will not, therefore, be able to accept this as a plausible end to Jamie, because the stated origin of the Cybermen doesn't square easily with radio and television serials. Indeed, until its reprinting in two separate 2008 publications, it was a story that most fans wouldn't have even been able to read, unless they possessed the original DWM issues. It's probable that most fans still don't know of the existence of this story.
The last issue in which the Sixth Doctor would be the "current" Doctor. Peri was given no farewell, but is merely absent from the next story, which is the first one for the Seventh Doctor. ("A Cold Day in Hell" does make passing reference, however, to Frobisher "missing" Peri, who is explained to be where she was at the conclusion of her televised travels.)
