Early 1915: He is recruited by the British Secret Intelligence Service (Canada, as well as several other Commonwealth countries were under British command for a large part of the war) and goes on several missions for them during the war.

Mother: Anna Carson (born 1872)
Father: Liam MacLeod (listed as unknown on his birth certificate)
Liam meets Anna Carson shortly after his return to the USA in San Francisco in 1891. The affair is brief and results in Anna becoming pregnant with Liam's child. Since Liam is not interested in marrying so soon after the death of wife, and knowing that she will have to raise the child on her own, she decides to go to Vancouver, Canada to live with her cousin who has runs a boarding house there. Liam agrees to send money each year to help her raise the child.
She arrives in Canada a couple of months before the birth of Mark. Not wanting to face the stigma of being a single unwed mother, she tells people that she was widowed and that her husband died in a horse riding accident. This is the story she tells her son.
When Mark is about three years old, Anna's cousin dies leaving her the boarding house. At the beginning of 1924, she is still living in Vancouver.
Mark finds out that is mother hasn't been truthful about the circumstances of his birth when he joins the Bureau of Investigation (B.O.I.), who obtain a copy of his birth certificate. He questions his mother about it on a brief visit to Vancouver and realises that she is unwillingly to talk about it, he starts putting two and two together. He works out that the mysterious benefactor who paid his college tuition must have been his father or someone who knew him.
Harvard Law School is unable to provide information on who paid the tuition and after following a few leads that didn't pan out, Mark decides to drop it for a while to concentrate on building his career as a B.O.I. agent.
