UNSPEAKABLE In Unspeakable, actor Gary Cole (In the Line of Fire, American Gothic) effectively drawls his way through Sandra Brown's latest sultry suspense. Using his natural voice throughout the story, Gary's exceptional acting skills and creative inflection bring an enlivened clarity to the characters. Recently escaped from prison, Carl Herbold heads for Texas to take his revenge on his stepfather, Delray Corbett, who had a hand in convicting him. Corbett fears Carl's reprisal will endanger the lives of his widowed daughter-in-law, Anna, and her small son David. The aging rancher finds an ally in Jack Sawyer, a mysterious drifter all too familiar with Carl's devious capabilities. Jack is drawn to Anna, and the deaf woman's silence speaks to his heart--a heart burdened with a painful secret that may keep the two apart. This superbly abridged audio packs the powerful punch of its author--all the way to a masterful end. (Running time: five hours, four cassettes) --Kate Breslin
