History Arouses Our Curiosity and Produces Entertaining Subplots

Indonesian Mount Tambora, not one of the tallest Mountains in the world, but a violent climax on April 10, 1815, proved Tambora to have the most powerful volcanic eruption in recorded human history. The explosive ash raised into the Pacific Winds and carried it over the earth, creating lower global temperatures. The results of that event were not felt until the following year and are now known as The Year Without Summer. The excerpt from That Wylde Woman has our main characters discovering the possible effects the explosion could have for England.
From Chapter 8:  Duke of Pangbourne speaking to Marleigh Barrett:

    The other evening you mentioned getting the family country estate back in shape. I discovered the scientist-explorer we discussed, Robert Evans, is giving a lecture tomorrow afternoon. The poster said he will be speaking about being on a neighboring island near Sumbawa, Indonesia, where the Mt. Tambora volcano erupted last spring. I understand he has some fascinating theories on how it may affect harvests and other consequences worldwide. Would you like to accompany me?”
    “Affect harvests here? From the other side of the world? Do you think that is possible? Seems a little far-fetched.”
    “It may be. We will not know until we hear what Evans has to say. He is lecturing at the  Geological Society of London.”
    “Indeed, it would be fascinating to hear what a scientist can theorize about a volcanic eruption affecting us thousands of miles and oceans away. Yes, I would be happy to go tomorrow.
