Cracking the Glass Ceiling, shares the life of Alison Roper, a somewhat headstrong young British woman of the 1960s. Much against her Lawyer parents wishes, she chooses to join the London Police Service, rather than the family law practice, policing at that time, being very much a Male dominated profession. With a total commitment and hard work ethic however, she rises steadily through the ranks, entirely on merit, and is seemingly destined for the very top, until one day in March 1974, fate, as it tends to do, intervenes, leaving one womans legacy to her peers.
