“Come Watson. The game’s afoot.”

At 6 p.m. April 9, Winchester’s Baker Street aficionado Tim Janes leads a book discussion about the second Sherlock Holmes novel, “The Sign of the Four.”

The story takes place in 1888. Its intricate plot involves service in India, the Indian Rebellion of 1857, a stolen treasure, a secret pact among four convicts (“the Four” of the title) and two corrupt prison guards.

It also introduces Doctor Watson’s future wife, Mary Morstan.

Holmes and Watson, aid Miss Marston on a dark and mysterious adventure involving a one-legged ruffian, hidden treasure, deadly poison darts and a thrilling race along the River Thames.

A ripping yarn.

Tim Janes’ reading groups are enlightening, entertaining, thoughtful and great fun.

Whether you’re a Baker Street regular or new to the canon, you’ll enjoy this reading group.

It’s free and open to the public.

Register to attend by calling the library, 859-744-5661, or by using the Evanced online registration system at www.clarkbooks.org.

There are still a few reader copies of “The Sign of the Four” available at the library’s circulation desk. You can call to reserve one.

From 6:30-8 p.m. April 10, and from 10-11:30 a.m. April 13, join Carolyn Pace and Bobbi Newell as they help you complete the Clark County Wellness Challenge by learning about the Whole30, an eating plan that changed their lives.

The events are free and open to the public, but again, register to attend by calling the library or using Evanced.
