Macbeth Underwater

I'm trying to cut back on my book-buying, so about an hour ago I was faced with a dilemma. In my right hand, I was holding Antonia Fraser's history of the Gunpowder Plot (which I will refer to tangentially when I teach Macbeth this term); in my left hand, I was holding the Diving and Snorkeling Guide to Scotland. I also had tucked under my left elbow a book about 18th-century England that I'd already decided was necessary and inexpensive enough to buy (for another class).

In the spirit of adventure, of Macbeth Underwater, I chose the diving guide, though I'm already noticing that drysuits are preferred over wetsuits -- sure, cold cold water -- and that snorkeling or diving in Loch Ness is not recommended (too silty, too little visibility; no warnings about monsters).

(There's always later in the week for the Gunpowder Plot . . . .)

There may be some broad hints toward that book-plot I've been wrestling with . . . Macbeth Underwater . . . .
