The relatives of a millionaire - the victim of a mysterious murder - get together at his house to search for his will, which he recorded on a record. However, one of them is actually the person who killed him, and will let nothing - or no one - stand in the way of finding that record.
In the most preposterous of circumstances, a millionaire dies in his bed. Was it suicide or was it murder? As his friends and family gather afterwards, they discover that the deceased has left a recording of his last will and testament but before it can be heard, a golf ball comes through the window, the "Rev. Makehan" (O.B. Clarence) comes though the door and the record is gone! What ensues is actually quite an irritating whodunit that features a house full of potential beneficiaries/criminals - including a young, quite chiselled Jack Hawkins - as we try to deduce how the old chap was killed. It's got plenty of secret passages in which we could/should hide whilst the annoying parson goes about his detecting. The staging is overly theatrical and the ending is just plain daft.
