I didn't have a problem with the general plot of the show. Egyptology is, and was, fascinating to the general public, and before people gave thought the the historic value of the things they displayed so carelessly, such things as mummy-unwrapping parties were indeed a popular pastime. And, as Brackenreid exasperatedly observed, they have dealt with werewolves and vampires and other gothicky matters, so why not mummies?
The first matter that I found disappointed dealt with Crabtree and his book. We have been watching this slowly evolve over many episodes, with Crabtree first flirting with the idea of writing a novel, then scribbling down ideas (usually at inopportune moments) and finally settling on a plot and beginning to write. Having completed his manuscript, the next step should have been showing him shopping around for a publisher--and likely dealing with several rejections--settling the contract, and perhaps arguing with an editor wanting to revise his precious prose. This episode breezes past all that; the book has been accepted, galley-proofed, and published. I did find it realistic that they would want to time the publication with the Egyptian show. I wondered if perhaps Crabtree had resorted to "vanity publishing"--he comments that he arranged to have a mere armful of extra copies printed to take to the show, which sounds a little odd. Perhaps his plethora of aunts pooled their resources to help him pay for the printing. On the other hand, later in the episode, he excitedly tells the station that the publicity has resulting in them making a second printing of the book, which sounds like a regular publisher. The whole business of the mummy raised several questions. To begin with--although I may be wrong--I find it difficult to believe that at that era of history they would have a well-educated female Egyptian scholar. Women didn't count for much back then. I suspect that they simply wanted a woman for Murdoch to interact with. Next, the comment that all Egyptian children are taught to handle cobras. I doubt that very much, especially the implication that they can somehow magically calm it to the extent that she could casually pick it up and drape it around her neck with no regard whatsoever for it's venomous fangs. It would have looked far more plausible if she, rather than the constables, had hunted the snake down, carefully captured it and tucked it away safely. Next, they would have us believer that the sarcophagus of this unknown but presumably royal person had come equipped with a secret access compartment. For what possible reason? An opening in the sarcophagus would risk damage to the interior contents. Next, they want us to believe that an archeological team, having carefully gone over every inch of the sarcophagus, failed to find that compartment. (Except for one man, who kept it to himself. Just when did he find it?) They also failed to notice that some of the writing on the outside was inlaid with an anachronistic material, thus giving Murdoch a chance to whip out one of his techie devices and show them up. Dr. Bajjali stated that there was no name on the sarcophagus, but at least one of the symbols--which were clearly visible to the naked eye--flatly stated the name, which I think was Maat.
There's also the matter of the snake's lunch (an Egyptian gerbil, which Dr. Grace first took for a mouse, despite it being four or five times bigger; she should have assumed a The implication is that the cobra was stolen en route to Canada, the killer having decided to fulfill "the curse". Apparently he decided on it in Egypt, and knew that A, the young Egyptian activist would be traveling on the same ship with them, B, that he had brought a cobra along for the ride, and C, after the killer stole it, he would need to provide said cobra with food, and thoughtfully brought along a gerbil, so as not to damage it's delicate constitution by feeding it a Canadian rat.
These absurdities aside, I did enjoy it. Murdoch is having to learn to deal with Dr. Grace's different style, and Dr. Grace is learning to deal with the constabulary. I especially enjoyed a scene in the morgue when, having made her verbal report to Murdoch, Dr. Grace claims a prior engagement and takes off, leaving Murdoch, who had plainly anticipated a good discussion, looking somewhat nonplussed. Crabtree, naturally, is quite willing to believe in a curse. He's having great fun with his book, and I loved his reaction when his female fans began to show up.
