Then women begin to disappear off the street, their bodies left under the Christmas trees that stand in front of London's most popular landmarks. Something links the women who have been murdered and Phoebe's maid, and Camille is determined to find out what the connection is before another woman is murdered.She realises there is safety in numbers, that she can do so much more with a team of resolute women by her side, so she recruits some of our old friends, Carrie, Elsie, Dorothy and Ida to help her discover what happened to Phoebe's maid, and why so many women are being murdered in such a brutal way.
