Dangerous Yesterdays — Arlene Hale

A stolen Stradivarius violin, worth a king's ransom, shattered the harmony of Deborah Sherwood's life. Suddenly the young high school music teacher could trust no one as she hunted the thief.

Could he be Terry Hoyt, the good-looking disc jockey who claimed he wanted to marry Debby, but suddenly made a very unexpected and suspicious decision to go to Europe? Or was the thief the handsome business executive Paul Lambert, whose lies about his past already had betrayed Debby's feelings for him? Or Debby's friend and mentor, symphony orchestra conductor Lorenz Mitchell, who was being blackmailed by a beautiful and mysterious woman? Or even the leader of a high school gang of ruffians who was out to wreck Debby's teaching career?

Caught in a whirlpool of menace, Deborah could be sure of just one thing. She was matching wits with a criminal who played the full keyboard of violence, and could turn a song of love into a symphony of terror.

Hero: Terry Hoyt
Heroine: Deborah "Debby" Sherwood
