The Maltese Penguin was the beginning of bonus releases that would become a common occurrence in Big Finish's monthly range where you can get them as subscription bonuses, and most of them aside from a couple of exceptions you can get on their own without paying a substantial amount on a specific subscription plan. I've been meaning to re-listen to this one considering when I listened to it the last time, I wasn't too keen on it.
Frobisher on a break from his travels with The Doctor has become a private eye detective, something that isn't coming along too well, after all, he's only saved a missing cat. But when a glamorous, beautiful lady comes on in, Frobisher is too quick to take on the job. Soon enough however he finds himself in the grips of Dogbolter, one of the richest and most corrupt individuals in the known universe.
Robert Shearman has written a really funny private detective story that almost defies the tropes, the genre is very well known for. It's a surprise to me that I didn't enjoy this initially, it's such a fun parody of the genre, with a great cast of actors and plenty of imaginative and hilarious humor. It's nothing amazing and definitely the weakest of his contributions to the company, but it's honestly such a laugh!
Overall: A really funny bonus release, that if you love Frobisher or hell Doctor Who comics in general, you should really give this a go! 8/10
