The pellet with the poison's in the flagon with the dragon!

OK, now that I've got the attention of all the Danny Kaye fans (yes, the headline quotation comes from the wonderful movie The Court Jester) . . .
Watch this space tonight for a brief review - part of a "blog tour" - of Jennifer Woodruff Tait's fascinating book The Poisoned Chalice. All I'll say now is that it's about the 19th-century shift in American Methodism from wine to grape juice in the Eucharist. And if that seems a small or limited topic, you won't believe how many other things come spilling out when Jennifer pulls that thread (or that cork?).
