Darrel and Sally Odgers were both born in Tasmania in 1957, and have been married since 1979. They have two grown up children, James and Tegan. Their first book together was published in the 1990s. The Jack Russell series is their most successful collaboration so far, and they thank their inspiration, Ace, for that: " She was lively, opinionated, busy, and always curious. She loved swimming, and playing ball games of her own invention. We were out walking one day and Ace, as usual, was sticking her nose into everything. "She's a real detective,"said Darrel. We spent the rest of the walk planning the adventures of a dog detective! When we wrote up the proposal for the series, we had Ace sign it with a paw print, for luck. It must have worked, because the Jack Russell: Dog Detective series has grown to eight books, with more to come."
