About Harrington Mystery

What is Harrington Mystery about?

A 3D detective interrogation game built with Three.js and integrated into the start.ng gaming platform.

Welcome to Harrington Manor, Detective. A terrible tragedy... His lordship was found lifeless at his desk after dinner. I am at your service, though I was fast asleep in the pantry from 9:30 PM onward.

Lord Harrington collapsed in his private study at 10:15 PM. A half-consumed glass of vintage 1895 Bordeaux was found on his blotter. Cause of death appears to be rapid poisoning.

Present your formal deduction to Scotland Yard. You only get one verdict—choose carefully based on testimony and physical evidence!
