How does the title “Contents of the Dead Man’s Pocket” contribute to the story’s suspense?

In the title, the words "dead man's pocket" create suspense. As we begin reading, we wonder whether the protagonist will survive his adventure. This sense of uncertainty creates suspense. Our curiosity is piqued, and we are motivated to continue reading.
The author continues the suspense by having the protagonist's wife attend the matinee alone. Apparently, Tom cannot accompany his wife, because he has work to do. As a result, the stage has been set for his possible "demise." We begin to question how, when, and where he will meet his final end, if, indeed, he is destined to.
Our curiosity moves us to read further. We discover that an important piece of paper has flown out the window. The figures on the paper represent almost two months of work for Tom. If Tom fails to retrieve the paper, it will take him two months to reproduce the calculations.
The author then has Tom climb out onto the ledge. He gives further harrowing details once Tom is outside. Accordingly, the ledge is about as wide as the length of Tom's shoe. Accordingly, Tom must move sideways. The author then tells us how far up Tom really is:

He saw, in that instant, the Loew's theater sign, blocks ahead past Fiftieth Street; the miles of traffic signals, all green now; the lights of cars and street lamps; countless neon signs; and the moving black dots of people. And a violent instantaneous explosion of absolute terror roared through him. For a motionless instant he saw himself externally—bent practically double, balanced on this narrow ledge, nearly half his body projecting out above the street far below—and he began to tremble violently, panic flaring through his mind and muscles, and he felt the blood rush from the surface of his skin.

In the passage above, the author uses tactile and auditory imagery to give us an idea of Tom's terror. Again, the title is foremost in our minds as we read. In the end, however, Tom survives. However, his harrowing experience is described in clear detail by the author. The words "dead man" certainly contribute suspense to the story.
