The Receding Past

Too tired at 11:26 PM to cope with a new text, I am rereading Poul Anderson's "Time Patrol," which I first read in 1960;

it was published in 1955 and is set in 1954;

Manse Everard, born in 1924, reads about the Addleton case first in a collection of Victorian and Edwardian stories, then in the London Times, June 25, 1894;

the Kentish village of Addleton has a Jacobean estate with a barrow of unknown age.

Notice how Anderson takes us back in time, generating a real sense of history:

the Victorian and Edwardian periods;
1894;
the Jacobean period;
a British barrow of unknown age...

Everard will travel first to 1894, then to that post-Roman British period, but first the scene is carefully set with Everard merely reading a short story collection, then an old newspaper, before embarking on his first mission for the Time Patrol.

And which story is it that refers to the "...tragedy at Addleton and the singular contents of an ancient British barrow"? (Time Patrol, p. 18)
