Toby was hired by Mary Steele to be the cashier at The Coffee Pot. Toby was a friendly, high-spirited young woman. Part of her duties involved making a daily bank deposits of the restaurant's profits. Unbeknownst to Mary, Toby was taking the cash to a horse race track where she and her boyfriend Mark Masters would place bets. Mark was a teller at Mary's bank, which enabled him to create false deposit receipts to cover their tracks. Mark received good tips on the races, and he and Toby were always able to replace Mary's money and keep the winnings for themselves. Toby bought several expensive outfits, which made Dick Tracy suspicious.
