Louisa (They Came to Baghdad)

In the novel They Came to Baghdad, Louisa is an intelligence operative and part of the team under the leadership of "Sanders of the River". Their mission was to maintain surveillance on Anna Scheele in London and prevent her from departing for Baghdad. While the rest of the team followed Anna around the streets of London, Louisa took the opportunity to search her room at the Savoy Hotel but found nothing useful. In fact Louisa's actions gave their game away as Anna had planted some traps in her room--a strand of hair on her camera case was no longer there. A briefcase, which ought to at least have Anna's own fingerprints did not have any fingerprints at all.

Louisa is described as a short plump woman.
