Query: Interesting plot, but no page turner.

The plot is believable and I think someday this could happen. But the plot to me took a long time to develop and the author didn't disclose enough clues early on to keep me interested. For example, I knew the Medan Diagnostics corporation was tied to the ProLif corporation The only link I had was through Michael Eliot. The other clues linking these two corporations together were too abstract to decipher so I was lost. I thought Alex was making leaps in logic by making sense out of these incoherent clues. The insurance policy envelops and the letter openers were big clues along with the printouts. However, there wasn't enough information disclosed by the author to link them together. I am not feeble minded and I like mystery novels, but this novel is only interesting toward the end because I wanted it to be over.
