Happy Birthday

When a party for a wealthy family’s ten-year-old daughter ends with the birthday girl dead, her older sister missing, and the father refusing to call the police, the detective isn’t exactly conventional. She finds herself at the site of the crime – a rented out old mansion – without any trace of memory. It’s the landlady who tells her that she is a private investigator who’s been hired to catch the culprit and bring them to justice. But how can she solve a murder when she can’t even deduce her own name? Was it one of the party-goers who did the young guest of honor in? …Or was it the ghost said to wander the haunted halls? Can she manage to find the missing girl before another tragedy takes…
