A professor murdered during office hours. A decorator enrolled in his course. Can she outsmart the killer who designed the perfect crime?

Madison Night just learned that business isn't sexy. She modeled her decorating career on a Doris Day movie, but after losing her company in a legal battle, the local banks are unimpressed with her unique sales angle. Determined to get her MBA, she attends night school - until her professor is found dead in his office after an intensely-heated lecture. Now the only degree she can think about is murder in the first.

While the college recovers, Madison's last hope for a loan is denied. The dean resumes the coursework himself, and Madison can't help wondering if the curriculum holds the clues to the murder. Continuing her education is not without risk; pursuing her MBA may leave her DOA.

Can Madison's sleuthing make the grade or will failure be a fatal lesson?

Teacher's Threat is the eighth captivating mystery in the Madison Night series. If you like smart protagonists, classroom controversies, and Cabot Cove syndrome or read favorites Cleo Coyle or Jessica Fletcher, you'll love Diane Vallere's engaging series.
