Madison, Wisconsin, June 2000. A man disappears during a routine day at the office. A woman finds a shoebox filled with cash, fake IDs, and a cryptic list. Two seemingly unrelated events with one unusual connection: William Shakespeare.

Seamus O'Neill, a local rock & roll musician, and part-time Ryder Detective Agency employee, investigates both events. As he carouses through Madison's nightlife, he determines the shoebox's purpose, deciphers the list, and explains the role William Shakespeare's works played in the man's disappearance.

But can Seamus O'Neill find the missing man?
