Despite the clever title, there's not a great deal of suspense here -- no more than is afforded by turning a page to discover the identity of artfully composed close-ups. Still, McMillan (Penguins at Home, 1993, etc.) has entwined several concepts and activities with his usual skill. Once the enlarged glimpse of a segment of a resplendent lollipop, a palm branch, a thorn, a steel drum, or a parrot's beak is decoded (in most cases the succeeding fuller image will be essential), the reader is asked what senses may be used to perceive it. These are given in both Spanish and English (""I see/Yo veo""), as is a recapitulation of the most likely responses with the names of the items (""smell an onion/oler una cebolla""). The handsome photos, featuring a pair of infectiously grinning primary-age kids, were taken on the island of Culebra, now a part of Puerto Rico. An attractive, well-constructed concept book.
