would it be possible to track down the source packet for this lecture and post it?

It should be noted that Reb Yudel does indeed give credit to Sir Arthur Conan Doyle for at least part of the Choshen story.

See page 5 of the preface and page 26 of the book Choshen Hamishpot discussed by Dr Leiman.

One can see it here:

1. Title:
   Nachum Lamm Dan Pekins, 

   Date: Aug 5 2009

   R' Leiman mentions this in his published article on the topic.

I enjoyed the lecture but it seems to be incomplete and ends with the beginning of the story of Johan Sylvester.  Is it possible to get the end of the lecture?
