Baby It's Cold Outside — Gemma Halliday; T. Sue Versteeg

Tessie King thought she knew all there was to know about tracking down bad guys after helping to find her father's killer. But when she's locked out of the Royal Palace Casino in South Lake Tahoe during an ice storm, she's suddenly faced with the task of tracking her own would-be assassin.
It's Christmas Eve, the town is encased in ice, and it's impossible to get an officer to respond without a dead body. With besties Tate and Britton in tow -- and head of security, Alfie, desperately trying to keep track of all three -- they set out to find the person responsible.
Will they find the attempted murderer before he can finish the job? Or will Santa be returning Tessie's gifts this year?
