Grimwood's impressive debut novel, Breakthrough (Ballantine, 1976), was heavily influenced by EC Comics, concluding its blend of science fiction, reincarnation and horror elements with a surprising and unpredictable twist ending. Towards the end of his life, Grimwood maintained a brief email correspondence with Hellboy screenwriter Peter Briggs, whom he contacted after seeing Briggs' review of Replay on the book's Amazon feedback page, revealed in an interview with Briggs in 2004.

One of his favorite things to do was for he and I to watch some old movie in the afternoon we did it often." He owned the first Betamax sold he had the largest video library I've ever seen. He did not like publicity and was actually quite shy. We had many dinner parties with him and some friends, and he would always be the one to keep the evening hilarious he was a great storyteller. Atwill described his friend's "free spirit lifestyle" and recalled, "He was a loner, almost a recluse. Married once with no children, Grimwood had friends on both coasts, including Tom Atwill, who is related to the actor Lionel Atwill. Some of his early novels were written while he was nightside editor at KFWB News 980 radio in Los Angeles, but the success of Replay enabled him to leave KFWB News 980 for full-time writing. Heading north, he studied psychology at Bard College in Annandale-on-Hudson, New York, where he contributed short fiction to Bard's student publication, Observer in 1969, graduating in 1970. In the mid-1960s, he worked in news at WLAK in Lakeland, Florida. He attended Emory College from 1961 to 1963. He graduated from Indian Springs School in 1961 and then spent the summer in Paris while studying at the Sorbonne. Grimwood took an interest in EC Comics and radio journalism while growing up in Pensacola, Florida. His sister, Teresa Panther-Yates, once described him as "a brilliant, beautiful human being who knew that the best of fiction has a message."
