First Class Murder (Murder Most Unladylike #3) by Robin Stevens - Hardcover Used

Middle Grade Ages 10-14

Daisy Wells and Hazel Wong are taking a holiday on the world-famous Orient Express - and it's clear that each of their fellow first-class passengers has something to hide.

Even more intriguing: there is rumour of a spy in their midst.

Then, during dinner, there is a scream from inside one of the cabins. When the door is broken down, a passenger is found murdered, her stunning ruby necklace gone.

But the killer has vanished - as if into thin air.

Daisy and Hazel are faced with their first ever locked-room mystery - and with competition from several other sleuths, who are just as determined to crack the case.
