Cherry's job as nurse to the well-known historical novelist Martha Logan would be an exciting assignment for any young and pretty RN. And it is doubly exciting for Cherry, for when the author goes to England to do research for her next book, Cherry goes along as companion nurse.

But the glamour of new acquaintances and the thrill of seeing famous historic places is soon overshadowed by disturbing events. Martha Logan and Cherry visit the Selsam Gallery in London—it is robbed of a fortune in art treasures. Several days later they are enjoying the famous Carewe private collection—when four masterpieces are cut from their frames!

Are the thefts somehow connected with their visits? Have some of their new acquaintances used Martha to help them perpetrate the thefts? Or is it merely coincidence that the places the two visit are robbed? Cherry thinks the evidence says NO.

It takes all the ingenuity and courage of the alert and pretty young nurse to fit the odd, baffling clues together and unmask the criminals in time to prevent another theft of priceless art.
