2-in-1 edition of the first two stories in the BLUE PETER AWARD-winning mystery adventure series about 11-year-old ace detective, Laura Marlin.

In KENTUCKY THRILLER, Laura is ecstatic when her uncle agrees to let her keep a horse after they rescue it from an overturned horsebox. But he has one condition - before he will allow her to adopt it they have to find its former owner, just to ensure that it hasn't been stolen. A visit to Newmarket to investigate the thoroughbred's origins leads Laura to the Kentucky Derby in the US and deep into the murky world of race-fixing.

And in RENDEZVOUS IN RUSSIA, Laura, Skye and Tariq are whirled into a breathtaking mystery adventure when they join the film crew on the set of THE ARISTOCRATIC THIEF about an art heist that could never be pulled off in real life. Or could it? Adventure and drama just seem to find Laura even when she's not looking for it.

This is number 1 in Laura Marlin Mysteries .
