The Lucky Lottery by Ron Roy

The Lucky Lottery is the L installment in Ron Roy's A to Z Mysteries series.  Dink, Josh, and Ruth Rose, the kid detective team featured in the series, solve the mystery of Lucky O'Leary's stolen lottery ticket.  What makes the plot even more interesting is that the ticket is a winning ticket, and whoever cashes it in is a millionaire seven times over!  The kid detectives are in a race against time to identify the thief before he (or she) makes off with the money.

If you enjoy mysteries like Encyclopedia Brown, you will probably like the A to Z Mysteries series.  Start with any letter of the alphabet you can get your hands on and read all 26!
