MysteriousPress.com has just made six Dan Fortune novels by Dennis Lynds available in eBook formats.
Two years later Lynds published the Edgar Award-winning Act of Fear (1967) under the pseudonym Michael Collins, which introduced his best known character: the one-armed private detective Dan Fortune. The Fortune series would last for more than a dozen novels, spanning three decades, and is credited with marking a more politically aware era in private eye fiction.
Besides the Fortune novels, the incredibly prolific Lynds wrote science fiction, literary fiction, and several other mystery series. He died in San Francisco in 2005.
