Winner of the #1 Story award at ScreamJam 2024, this immersive HTML5 browser game lets you step into the shoes of Sheila Watson, the brilliantly minded daughter of Dr. John Watson. After the untimely passing of Sherlock Holmes, Dr. Watson retires, but his legacy lives on in Sheila—a keen investigator with a tenacious spirit.

As strange, spine-tingling events unfold in the shadowed alleys of 1888 London, it’s up to you to solve cryptic puzzles, interrogate suspects, and uncover hidden truths buried deep in the city’s underbelly.

Procedural clues, devious suspects, and cleverly placed red herrings ensure every playthrough sparkles with surprises. Will you catch the midnight killer and reclaim your family's legacy? With each deduction and dialogue, you'll engage in mind games worthy of Holmes himself. So gather your wits, sharpen your instincts, and become London’s next great detective. The case of Mister Jack awaits—are you ready to crack it wide open?
