I guessed it was Colonel Mustard in the Study with the Dagger

Rating: 8/10 (3 January 2020)

Outstanding performances by the all-star cast, great directing and cinematography, and the score was fitting for this amazing whodunit story, but I felt the screenplay needed some trimming and/or the pacing sped up in the first half of the film. The 130 min run-time felt too long and was evident when the perfect pacing started towards the ending. This film should've been no more than 100-110 mins. Nevertheless, a really entertaining story of mystery, thrills, suspense and a touch of comedy in the right places.
