MURDER AT THE REHEARSAL by Colin Barrow
The play is set on stage at a theatre which is owned by a guild of theatrical groups in a town. Owning the building means the various groups use it for meetings, construction, sewing, rehearsals, etc. Here, the drama group has met to begin the first rehearsal on a bare stage with no set built or proper furnishings. After the arrival of all, the director attempts to start the first rehearsal of a play. This rehearsal comes to an abrupt end when Mary dies sat in her chair on stage. As the actual play progresses over some days, the mystery of Mary’s death it becomes apparent that she was poisoned.
One by one other members of the cast are murdered whilst the police investigation goes on. This becomes a real brain teaser for Detective Shaw, as some murders happen when he is in the building! The story twists and turns giving mystery along the way until there are only two characters left, Detective Shaw and Rory Jones. Surely one of these two is the murderer, but the play ends with everyone including the Detective dead!
