*The Case of the Crimson Kiss*: Perry Mason deciphers (among other things) the mystery of the "crimson kiss" on the forehead of a murder victim...
*Fingers of Fong* finds Dick Sprague matching wits with a Chinese murderer...
In *The Valley of Little Fears*, a man and a dog have to come to terms with their fears and cowardice - and, perhaps, more...
*Crooked Lighning* tells the tale of a gem agent pitted against a gem thief called Crooked Lightning. With the special Gardner twist in the tail...
And *At Arm's Length*: Of Jerry Marr, a private detective who has to "create" his clients in an economic depression. Whose "tough-mindedness in his approach and brilliance in his deduction ... suggest a step in the evolution of Perry Mason."
