Another Time Patrol novel with Everard Manse. A lot of this is taken up by a newer agent, a woman named Wanda Tamberley.

Manse is getting a bit worn down by the whole time policing thing, particularly given there is a faction with similar technology opposing them to their own ends.

Wanda herself gets a bit attached to those she is interacting with in 13000BC.
