A real gem from the collection is THE ULTRA SLATE MESSAGE by
Dr. Daley. It’s a clever slate trick in which a message mysteriously.
appears on one of 4 slates that have been shown clean by the
Performer moments before. I have been using this for a long time,
and like it better than the standard set of two-spirit slates with the
movable flap.
At the Parlor of Mystery in Lindenhurst Long Island, we produce
a special Halloween show each year. Last year it was my turn to
emcee. I was planning to produce a message using Dr. Daley
method. However, after reviewing the other performer’s setlists,
I found that someone else was planning to use spirit slates in his
routine to produce a message. As the host, it was my responsibility
to defer and adjust my plans so that there was no redundancy.
So instead of producing a mysterious message, I used Dr. Daley’s
method to produce a spirit photo. I was happy with the way it
played and pleased to share my adaptation with you.

Most importantly of all, it really LOOKS authentic – but then, of course, it really did come from Holmes ‘s Murder Castle(!?!). It’s the sort of prop which adds the right amount of “atmosphere” to a performance; a mixture of intrigue, puzzlement, authenticity whist being ‘unsettling’. It’s very well constructed and aged. Importantly, it doesn’t betray the devilment that hides inside. As with all such props, it is what you the performer makes of it and with it that matters. Let HHH ring it for you – if you dare.
