Liars all

the long version

"Brodie Farrell has been asked to find some strange things in the course of her business, but this time it's personal. She's searching desperately for a cure for her baby's cancer. Attempting to keep the business afloat in her absence, Brodie's devoted friend Daniel Hood undertakes the hunt for a necklace stolen in a murderous robbery. Typically, he keeps looking when a wiser man would have given up. After the first attack on him. Certainly after the second. Meanwhile Brodie's partner, Superintendent Jack Deacon, is facing his old adversary, Terry Walsh, who presents Deacon with an agonising dilemma."--Publisher description.
