Baker Street Irregulars discussion

Help needed!! Thinking of writing a Holmes and Watson book which will be a conversation piece where they discuss subjects from A-Z. Any suggestions for subjects?

Mmm. Will think about that and come up with some ideas.

Okay. A few thoughts, in not particular order.

A - Apiary - maybe Holmes explaining why he wants to keep bees.
P - Phrenology, Philosophy
Z - Zen Buddhism - Holmes must've come across it during his travels.

Still thinking of others.
