Kendrick was an American lawyer and executive who became a full-time writer in 1932. His first mystery novel, Blood on Lake Louisa was published in 1934.
In 1914 Kendrick was the first American to enlist in the Canadian Army, one hour after that country declared war.
He married Edythe Stevens in 1919 and Jean Morris in 1971, and became an executive and manager of hotels and publishing companies. Kendrick was the organizer and only sighted member of the Blinded Veterans Association.
He was also a founding member of the Mystery Writers of America and held membership #1. In the 1960s he retired to Florida.
There are only three stories in this book; the rest is padding ("previews" of other Maclain books). The stories are good, but they hardly add up to a full volume's worth. If there are no more Maclain stories, they could have included some non-Maclains by Kendrick.
