First Lines to First Paragraphs: NOW would you read on?

A big thank you to hope, BECKY, and Lisa Ricard Claro for your comments on yesterday's post. I think we all agree that none of these lines was particularly sparkling. Nor, for that matter, was the opening line of the wildly popular winner of Nathan Bransford's first paragraph contest: "I was born during an electrical storm."
What these first sentences all have in common, however, is that they are SHORT.

Now, I'm sure many wonderful stories start with LONG sentences. (I'm just too lazy to do the research just now.) But what a short sentence does is anchor the reader. A character ("Priscilla;" "Edith Goodnough") is named; or an "I" narrator comes on board. "Unsolved mysteries," is of course from Agatha Christie, the start of The Thirteen Problems, starring Miss Marple. Agatha Christie gets away with this because she's well, Agatha Christie. She's a "brand" and readers pick up her books expecting to solve puzzles written in (now) old-fashioned prose.

Here's a list of the other openers, and who wrote them.

First Lines: Would you Love 'Em, or Leave 'Em?

This whole first line/first para thing has got me jazzed. So this morning I crept into my lair (a.k.a the study/library/furnace room) and snatched five novels at random off my shelves. Thought I'd test those first line waters on you. Would you read on?

1. "Priscilla lived in a studio apartment."

2. "Unsolved mysteries."

3. Edith Goodnough isn't in the country any more."

The following two are prologues, which many agents claim to hate. (But heck, a whole barge of books open with prologues. I guess they just have to be written well.)

4. "I haven't laid eyes on the island in several years."

5. "It's hard being left behind."

Can anybody guess who the writers are? (I've listed them below. I've kind of cheated, because each of these had either speaker denotations or chapter headings/locations and dates which may have added to you being able to "spot the writer.") And competitive ol' me wants to see if you can guess. There'll be a big old Badge of Honor waiting for the first commenter who gets it right.

Here are the writers. Which lines did they write? Kent Haruf, Dennis Lehane, Audrey Niffenegger, Agatha Christie, and Tom Robbins?

(I'll reveal all tomorrow, and extend each line into a first paragraph. I think you'll find it interesting, in each case, to see what happens.)
