In Book #5 of The Liffey Rivers Irish Dancer Mysteries, 14-year-old Liffey Rivers is miles above the earth, en route to Amsterdam, relieved that her harrowing experiences in South Africa are finally over, when she notices that a man on the plane is wearing identical Italian leather shoes worn by a man who had delivered a picnic basket earlier in the day at the Johannesburg Feis. She had not seen his face, which had been masked by over-sized sunglasses but she had noticed his shoes.When she had opened the basket, a Black Mamba snake popped out. Paralyzed with fear, she tried unsuccessfully to rouse the sleeping detective her father had hired to protect her on her way back to the U.S. and then realizes that the shoe man has struck again. Sick with fear and realizing that she is trapped miles above the earth, she must once again employ her Irish dance training to save her life and the life of her unconscious bodyguard. Months later, she takes an idyllic Alaskan cruise with her family and best friend from Ireland, Sinead McGowan. The cruise itinerary includes, in addition to exciting shore excursions, her first boyfriend and an Irish dance competition in Anchorage. Liffey Rivers sets sail, unknowingly heading to a rendezvous with her worst enemy, on the shores of the Arctic Ocean.
