When Phyl is dragged along to the Girl Guides by her younger sister, Annie, the last thing she expects is the adventure of a lifetime. Then her Guide captain offers her a job as a messenger for MI5. Phyl is desperate to help the war effort and is thrilled to be working with spies. But she can’t seem to do anything right in the eyes of the grumpy Major Warren. When he suddenly disappears, Phyl and Annie suspect that he may in fact be a double agent. The two sisters must solve the mystery of his whereabouts, before it’s too late. Luckily their friends from the Rose Patrol are ready to help...

She joined the Brownies aged 7, and still volunteers as a Brownie and Guide Leader and an Ambassador for Girlguiding South West England. Her Guide unit has never discovered a murder (or at least they’ve never admitted it…).
