The actress/writer made her film debut in 1936's The Murder of Dr. Harrigan and went on to star in 50-plus films in the following decade, including Drums Along The Mohawk and They Dare Not Love.
Linaker also co-starred in a series of Charlie Chan films.
But, after marrying writer Howard Phillips in 1945, the actress became a screenwriter, often teaming up with her husband to create TV and radio shows. Her biggest success came under her married name, Kay Phillips, when she co-wrote The Blob, which was to become an early film for movie icon Steve McQueen.
Linaker died in New Hampshire.
