Bloodlines

by Susan Conant

Published 1 December 1992
Normally Holly winter wouldn't be caught dead in a place like Puppy Luv -- a mall pet shop that's no doubt an outlet for the puppy mill industry and a hotbed of forged papers, broken promises and mistreated animals.  But a hot tip on a malamute pup suddenly has Holly charging to the rescue and panting to put the owner out of business.  Trouble is, she's not the only one who has a bone to pick with Diane Sweet.  in a matter of hours the puupy love proprietess is gruesomely murdered.

When Holly links the killing with the disappearance of another malamute -- an adorable live wire named Missy -- she digs up startling evidence that soon leads her into the fiercely competitive and deadly underworld of dog breeding.  A place where her biggest fears are realized.  And where her animal instincts are all that can save her.

Ruffly Speaking

by Susan Conant

Published 31 March 1994
Holly Winter’s a Dog’s Life columnist on the wrong side of thirty, a canine-loving detective sniffing out crime on the streets of Cambridge. Holly is a dog’s best friend—and a murderer’s worst enemy . . . 

They might be less famous than guide dogs for the blind, but hearing dogs are no less invaluable to their owners. Holly Winter discovers this well-kept secret when she interviews Stephanie Benson, a hearing-impaired priest, and her canine companion, Ruffly. A hardworking, reliable mixed-breed, Ruffly lends an ear with ringing telephones, doorbells, smoke alarms, and the other everyday sounds on which Stephanie’s livelihood—and life—depend.

Ruffly and the rector have just moved into the house of Holly’s recently deceased friend, Morris Lamb, whose life-loving and dog-adoring ways left no clue to his sudden and untimely death. Then Ruffly begins tuning in to something more than mere mortals can hear. And when Holly follows the dog’s lead, she picks up the unmistakable sound . . . of murder.

“[Susan] Conant’s readers—with ears up and alert eye—eagerly await her next.”—Kirkus Reviews
