Rafferty and Llewellyn 06 Dying For You

Rafferty becomes chief suspect in his own double murder inquiry
Detective Inspector Rafferty signs up with the Made in Heaven dating
agency, discreetly using an alias. He's very much charmed by the first
two women he meets, but love is fickle. Both of them are dead by the
following Monday. Now he's got to double up the ingenuity required to
solve the crime with the slyness to avoid being found out.
