What it is about
A locked display. A missing ceremonial key. One timeline that does not lie. The Grand Bell Hotel is preparing for its anniversary ceremony when the antique Founder's Key disappears from a closed display case.
Three people had a reason to care about the key. Only one person's account conflicts
with the independent records. The Missing Hotel Key is a downloadable print-and-play detective mystery for solo players, couples and families. Read the case file, compare the evidence, narrow the removal window and record your conclusion before opening the solution. What is included an 11-page illustrated Player Case File; seven evidence documents; three persons of interest; a printable working timeline and answer sheet; a separate 2-page Progressive Hints file; a separate 4-page Solution Guide. How to play Download the Player Case File. Print it at 100% scale or read it on screen. Review the evidence and complete the Detective Answer Sheet. Open Progressive Hints only if you become stuck. Open the Solution Guide after recording your answer.

or the difficulty of the deduction would be especially useful. Credits and disclosure Designed and published by CaseQuest / ProjectLab .
