Osgood:

A million thanks!  When I first commented a couple weeks ago about the various flavors of Batman during the Schiff era--weird transformation Batman, family Batman, imaginary story Batman--and how my favorite was the detective Batman--I was struggling to recall the exact elements of the Madcap Island story, which I read 50 years ago.  I had a kind of vague memory that there was a giant billiard table, and there was some Batman mystery than involved putting nail polish on a dime....wow, it was great to see this story again and I am surprised at how much I recalled about this story from half a century ago.

Now, if I could only remember the computer passwords I used last week.....
