A Trail of Fire is a collection of short stories written by Diana Gabaldon from the Outlander word.

The short stories are:

• In Lord John and the Plague of Zombies, Lord John Grey is posted to Jamaica to assist the Governor as he faces a most unusual kind of uprising among the colony's slave population.
• In The Space Between, Jamie Fraser's step-daughter, Joan, is on her way to an abbey in Paris to become a nun - but when she meets the Comte St Germain, a wealthy French aristocrat rumoured to deal in the occult - she discovers her destiny lies on quite a different path. (also published in The Mad Scientist's Guide to World Domination)

• In The Custom of the Army, Lord John Grey is summoned as a witness in a court martial in the wilds of Acadia, only to find himself playing a crucial role in the Battle of Quebec.

• In A Leaf on the Wind of All Hallows, a WW2 Spitfire pilot called Jerry MacKenzie crashes near a stone circle and wakes up in the eighteenth century. Can the strange man he meets - who impossibly seems to know him - help him return to his wife and baby son before a terrible fate overtakes them? (also published in Songs of Love and Death)
