2-book thriller set “Never Kill a Cop” & “Secret Mission To Bangkok” Vintage paperbacks

"The Bedside, Bathtub, and Armchair Companion to Agatha Christie", by Dick Riley and Pam McAllister, published in 1979 by Frederick Ungar Publishing. First edition, signed by both editors. This is a large, quarto, size paperback in pictorial covers, profusely illustrated in black and white throughout, 4 glossy pages in full color, signed by both editors on the title page, 330 pages including an index. This is a "very good" vintage paperback. The text block closes squarely and tightly, the lower page corners of pages 171-177 have been mis-trimmed at printing, and are folded up, otherwise, no loose, torn or folded pages from normal use. Binding is tight, not cracked or rolled. Text block edges lightly tanned, but internally the pages are bright. Over all edge wear with come chipping on covers, front cover slightly sunned at spine edge. Front cover relatively free from creasing, back cover has some light crease toward outer edge (see accompanying images). Overall, a very pleasant, special volume. Sure to make a special gift for the Miss Marple / Christie / Poirot fan in your life! Perhaps you! See accompanying images for full condition details. Will ship promptly, carefully packaged.
